Mechcommander 2 playback trouble

[deenmon]

I was wondering if anyone had some advice on why my copy of Mechcommander 2 plays slow and choppy. I've had that problem with Mechwarrior 3 but when I used the no-cd crack it was OK. When I applied the fixed exe/no-cd crack for MC2, I thought it would help but it still plays choppy and slow. Anyone know what I can do? My specs are OK; I'm running an AMD 1.2 ghz with 256 DDR RAM and this is the only I can't work out the issues with. Thanx in advance...Deenmon.
