When I got entrenchement, I uninstalled the beta to play my previous game, but Sins crashed.

To cut a long story short, I've been uninstalling and reinstalling Sins and Entrenchement ever since and it crashes upon startup. Every time I uninstall and then reinstall it gets worse.

Entrenchement would crash if I would try to run it through impulse but not through start/programs. Now it doesn't even work through the launcher.

Now it no longer minidumps. Instead it says it cant find fmod.dll and doesn't work. I have done system restore twice to a date before I got entrenchement and that hasn't solved the problem.

Does any one have any ideas as to what I can do?
