If you launch Lightroom holding down the alt key and choose to create a new catalog, does it open normally?

If you accidentally tried to create a new LR catalog and selected an existing picture file (!) instead of a not yet existing folder name, LR will crash afterwards at each start, and even holding down Alt/Ctrl key will not work in this case.

If this happend to you, try to rename the file that causes this (it should be displayed at the start of LR "opening catalog..."). Then LR should start normally, creating a folder with the previous name of the picture file.

By the way: In my opinion, this bug should be fixed as soon as possible, because I suspect that it causes a lot of work for the adobe support ;-)
