Doesn't sound good did you install properly from scratch?
and then install the superpatch and the minipatch if this is just Betweean Heaven and Hell?
If you just copied it from a backup or something and then edited registry we can't support that. So make sure you install properly rather than manual editing of registry.
Also see that FAQ section I mentioned it explains you may need to set to run in xp compat mode if issues still.
You may also need to install DirectX9 as some components are missing from Windows 7 DX9 compatibility.
