You can rescue your data at any time by copying it out externally from the good profile or using Copy & Paste - in Windows Recovery Console
or Paragon Rescue CD Free Edition 11.0 Free.
If this problem began after you have a Restore Point then that may be the way to resolve it.
You seem to be limited by what you can do by your IT dept which should handle this for you.
Normally with a bad profile if a new one can be established which works then you can migrate to the new one and delete the old one. If the new one has problems then I'd consider a Repair Install
or Clean Reinstall - Factory OEM Windows 7
But you should clear this with your IT department, which has all of our hands tied until they act.
