Keep the Melo 2, you might work your way up to it sometime down the line. Never say never.   
With vaping, nothing remains the same and your tastes and preferences will change. The Melo 2 might be just right... later on.

I'm SO glad we could help out
There are a lot of awesome people on this forum that have helped me tremendously too. 
Happy vaping,

Ok made a mistake. It was an Eleaf 30 and it is the one that died. The new TC60W  is what a bought to replace it. I used the EC 0.3ohm that was pre installed with the Melo 2. It seems so harsh and not what I'm used to. I will watch the videos you suggested and see what I can learn from them. This is just so different than what I am used to and  seems to be so complicated. I do not understand anything about the temp control stuff. 
You guys are awesome. Thank you so much. Just switched to my nautilus mini and lowered down to 7 worked my way up to 11 and it's perfect. Who wants a Melo 2? I have no use for it. 

How to Use
Switch display mode:
Keep pressing upside and downside of the adjustment button simultaneously for
two seconds when the device is off, the screen display will rotate 180 degrees. You can view the screen from
two different angles through this operation.
Switch among VW /TC-Ni/TC-Ti modes:
Long press the menu button to switch modes.
1) In VW Mode:
Adjust wattage:
In VW mode, the output wattage can be adjusted from 1W to 60W by pressing upside or
downside of the adjustment button, upside to increase and downside to decrease. Long press upside or
downside of the adjustment button can rapidly increase or decrease the wattage level.
 
These are the directions to set it as earthlink suggested

I'll chime in a little help here... As everyone said earlier, the simple solution is to use your Nautilus Mini on the new mod, switch it to Wattage-mode, and use somewhere between 9-12W, which is probably what you were using on the old iStick 30W?  This is the simplest solution and you'll be happily vaping the same as you were before the iStick 30 died.  There's no need to sub-ohm or use TC-mode unless you want to, which leads me to this...
When you drop resistance of your coil... you also have to lower your Nicotine strength by roughly the same ratio.  For example, if you were using a 1.8 Ohm coil and 8mg Nic strength, and want to use a 0.8-1.0 ohm coil... you'd want to drop your Nicotine down to 4 or 5mg.  Dropping from 1.8 Ohms down to 0.3 Ohms is a major drop... (over 80%) so you'd want to drop your Nicotine level down to 1 or 2mg to prevent harshness and to maintain your "normal" Nicotine dose-level (Nicotine absorbs faster into the body as it gets hotter).  You'll also want to increase your VG ratio to 30/70 PG/VG as a good ballpark for sub-ohm vaping.

No it wasn't a waste of money at all..you just need to use your nautilus mini on it instead of  the melo 2 which is a sub ohm tank.
You're fine  
Lets start over. Use your Nautilus mini tank and put it on the 60.  Drop your watts down to around 9.0 and slowly work up until you find the correct setting for you. @Tam can probably help you more on this. I know she uses a coil similar  to yours on her  Aspire Triton V2 tanks I think she sets it around 9.7 but I'm sure you might have a different setting since no one vapes exactly the same.
Don't give up! we'll get it figured out

The Triton V2 tank would work for you too I believe.
You might read this thread there's a few people who vape MTL and with different tanks that might work for you. Tank suggestions
I vape sub ohm so I'm not that versed in these but try the Nautilus about 9w until more folks chime in

Also, which Aspire mini were you using and what was your nicotine level (presuming you are vaping something other than 0 nic eliquids)?  If you were using the Aspire Nautilus Mini (I believe that was the only "mini" Aspire tank available a year ago, but I could be wrong) you were likely using coils that were 1.6 ohm or 1.8 ohm.  Dropping to a .3 ohm coil is a whole different world.  Aside from the fact that sub ohm vaping (vaping with a coil resistance less than 1 ohm) isn't necessarily for everybody, a higher nicotine content will definitely contribute to harshness.
