Just bought the game nad have played for 3 days. From the first day it started to give me black screen, with music and cursor. i can press f11 and f12, alt+tab out of gw2 and it reponds to alt+f4… ive tried everything. Repair, re-install, fixing gfx driver, changing settings, running full screen, windowed-mode and so on… and still, it goes black. sometimes i can play for 5 minutes and sometimes over an hour. Wonderful game but this kind of sux…
