There were files in the dynamic folder when I deleted it.


[color:"orange"]Have you tried running the game in compatibility mode, assuming Vista includes this feature? Try right clicking on the div.exe program file, select Properties and look for a 'compatibility mode' tab, or something.[/color]

I tried it under different 'compatibility modes', and it still has the same problems for me.

Have you checked for Windows updates? Vista drivers are not very mature, so updates or patches may address compatibility issues.[/color]

Fully up-to-date here. Updated graphics drivers and such to.
