Revit won't load

[bob.86982]

I updated to Revit 2011 about two months ago and everything has been fine, but today as I was creating a pdf file of a sheet while I was in the print dialog I accidently shut down revit thinking I was closing the print dialog. Now I cannot open revit, it stalls and when I go to task manager it says SECSplashWnd not responding and when I cancel the task it says autodesk revit not responding. I have tried restarting the computer, opening from the desktop icon, the programs file, and from a project file and it will not open.

Help!

After I posted this I went to lunch, when I got back I tried again to start revit and it opened. I still don't know what the problem was but at least i'm now back in business.

I'll bet it was the Communication Center messing you up.

Don't worry that it say AutoCAD, I've seen this fix Revit, too.
