Nothing helps. Currently, I'm re-installing to see if that rectifies the issue.
Thing is, my system was able to play the beta more or less flawlessly. I've included my specs below- please help me work my way through this as soon as you're able, I want to start playing my Demon Hunter. Plus, I've a review to write.
OS: Windows 7
RAM: 4 GB
Graphics Card: Nvidia Geforce GT 540M
Processor: Intel Core i7- 2630QM (2.00 GHz)
