Blender Crashes opening a specific .blend file

Hello, I have blender 32bit on Windows XP. Using Blender 2.63, I have been working on a character model for several days with no problems. Today, I tried to open the file again as usual and blender crashed on me. I tried a few more times and the same thing. Finally, I thought it could be a problem with this version of blender, so I uninstalled it and upgraded to Blender 2.65a. I am still having this problem when trying to open my project. Please help!

Hi, there are .blend1 .blend2 with the same name, these are backup files.
Rename it and try to load.
Try to append your object in a new file.

Cheers, mib.
