I have been using LR 2.6 for a few months and it was working fine. Today, whenever I try to switch to the 'Develop' module, the application crashes. No error messages, no warning, nothing. I tried with a new catalog, and deleteing everything from {username}\Application Data\Adobe, same problem. Now I can not do any work. I am using WinXp. Anything else I could try besides reinstalling?
Try renaming the file "Lightroom 2 Preferences.agprefs", so LR will build a new one when it starts next time. This might help.

Sorry, just realized that this might have happened already by your delete.
