got the same problem here, won´t start at all.
I tried the following:
-downloading and installing Dx9c (again), restarting, didnt work
-turning off Norton Anti Virus, Black Ice Defender and all other programms and also shutting down processes that still ran in the background connected with these programms,disabling virtual drives, didnt work
-uninstalling it, downloading and installing it again (tried on both of my harddrives), didnt work
Got Win2000 SP3, 2.4 Ghz P4, there are over 2 GB free on drive c and around 20 on drive d.
No similiar probs with all other games I tried so far expect one: Shadowwatch from Red Storm...but thats kinda old (2000 or something).
update:
I got hold of an older version 0.600 (??) and this one works...at least I get the start menu (opposed to the actual version)
