ReInstall Win 7 Lost Custom Shelves.

My machine choked and I had no choice but to reinstall Win 7 Pro.

I lost some of my documents/Maya scene files but not all

The issue now is can I rescue my shelves somehow? No backup, I'm too poor for that.

If no I can start fresh, but would be nice to find those shelves.
thanks
Dan
oh, using Maya 2011
Win 7 Pro
