Guild Wars 2

Hiya, Yesterday I purchased a new hard drive, so put it all together and before removing i copied the big . DAT file for Gw2.

So my plan was to, go to the website start the launcher, sign in and then pause/cancel then replace the install file. But the launcher will not work at all. It will open up download some information then immediately disappear. I had a look on the forums to see if I could find something similar there was a suggestion to rename the file from Gw2setup to simply GW2.exe I tried that and the launcher just freezes. I also read about some other fix with temp files and all that jazz but there are no temp files as it wont go that far to create a download directory. Anyone any ideas please?

OKay found the problem, but this roots back a long time now. I own a ATI Radeon 6870 hd card a while back they released a driver that causes mass strobe flickering in 2d environments and that was never officially fixed, The launcher will not load without the latest driver, As I’m typing this my screen is flying all over the place and if i roll back to fix the issue the launcher will not load! Ahh this is so frustrating. There is no flickering at all in games and things with 3d enviroments. Anyone any ideas I’ve looked on the forums and the only suggestions is to overclock which I don’t need to do and don’t want to either. Thanks!
