Well I recently upgraded my system from Win 98se to WIN XP professional.

I had AOE II: The conquerors installed in Win98 which workeds perfectly.
But now when I start the game The screen just keeps on flickering. I tried re-installing the game.
but it does not work. I had the same problem with Windows 2000 executive server,
which I had to completely remove so I could play AOE II. I downloaded a patch from Ensemble studios site.
but when I run the patch it says Commercial version not installed. Now I received the AOE II cd as a gift,
So I cannot be certain of its authenticity or genuineness.

Is there Anyway I can run the game which works perfectly in win98 in Win XP. I have tried, changing screen resolutions.
also Monitor refresh rates, and other weird solutions like even changing monitors with another machine.

my config is

PIII 1.1 GHz
128 MB SDRAM
i810 motherboard with 4m on board AGP (at least thats what it says on manual)
40 Gb HDD


Please if you have any solution do reply...
