Just to preface--there's no 2.0 update for Dread Lords, which it sounds like you have--the minor update that dropped alongside 2.0 for TA/DA is just Vista compatibility stuff for the most part. So if you're not on Vista, you don't need it.
Thanks. I do have just Dread Lords (been meaning to look into getting a combo TA/DA pack), and I didn't really look closely at update details, just ran Impulse and let it do its thing.
In any case, post the debug.err file's contents from the folder where the game is installed at, it should give details about what happened when it tried to start.
Well, this is interesting - really nothing there, and what's there is WAY out of date:

That certainly seems odd, as I've reinstalled GC2 3 times in the last 2 weeks. The date on the file itself is 11/14/2008. (And my PC's date is correct.) That date is probably when I first installed the 1.5 update, and there have been plenty of crashes since then.
