Endless Error on start up

After accidental SW 2010 SP3.1 shut down, in attempt to start i've got endless chain of messages "An error has occured and SolidWorks needs to re-start".

SolidWorks Rx find no errors. After complete removing of all versions, and reinstalling SP2.1 from disk nothing changed.

Have anyone ideas? Please help!
