InCopy crashing on launch

[winkler.dane]

Every launch of InCopy CS5 on a Win7 x64 machine I get this crash error.

Today, this is new (ObjectModel.dll)

Yesterday is was public.dll. 

I uninstalled InCopy, cleaned up the hard drive and reinstalled it. The crash persists. 
Does anyone have any ideas to try?

CS5 is almost 10 years old. There's no telling what the issue is but the only suggestion I can give you is to try resetting your preferences.

That did the trick, thanks. 

Wish I had thought of it sooner!
