I had the same issue not so long ago, but I followed the steps mentioned by Adversarious1 in the same order and fixed it. At first, I thought it might be because of the computer (mine is really old)and tried to install a free registry repair to clean the malware, but after this nothing changed, I still couldn't connect the G-Priv. After a while searching on different forums I found this post as well as some other similar ones with the steps described above, so luckily I could make it work.
