It might be worth repeating the above procedure but also removing the 
Mathematica directories inside "Documents and Settings". Using back 
versions of Mathematica is a normal thing to do, and should not cause 
problems - even if you launch 6.0 and 7.0 at the same time.

It would certainly help if Mathematica were a bit more informative about 
what it was doing when such errors occur!
