Update.
After I run into a dozen or more freezes on the weekend playing the new first ward stories I found this thread here with the amd vs cox problems. To make it short the new freedom client has still issues with the amd drivers.
Downgraded to the 11.4 ati drivers and after a few hours not one single crash. You really should find and fix that problem asap or have fun with it when you open the floodgates for the f2p crowd, considering that nearly 33% use ati cards.......... 
Random game client freezing. Can't attach report files and forum has problem with to many <>... chars.
If you need more information sent me a pm for the full dxdiag or any other report file.
