I just Upgraded my os from win98se to win XP professional. Now my AOE II is all messed up. The screen keeps on flickering. The game starts all nice and well. But immediately starts flickering. My config. is PIII 1.1 Ghz i810 Motherboard. 40 Gigs HDD/ 128 SDRAM So where can the problem be. Rest all other games work well. But only this game has problems. Also AOE I & Its expansion have the same problem.
