I have some difficulties while playing MA. The first is trouble with music. In few seconds after launching the game music becomes faltering and plays with delays. I tried to reduce sound hardware acceleration in DirectX properties, but it didn't give any result. The second is that sometimes in-game cursor disappears and i have to resart the game quiting to windows.
My sytem conf. is: WinMe, P4-2400 (with on-board sound AC'97), 512 Mb RAM, GF4 Ti4200 with 128 Mb.

open your settings.ini file and change SoftwareCursor from 0 to 1 (this might fix problem with cursor)
Also try Change next options:
CPUSharing from -1 to 1
and
UseHardware from 0 to 1 (in sound section)
this might help with music

Thanks! It helped!
