Ouch! That's pretty bad.
So, are the file extensions renamed indeed?
If so, try renaming them back (just a few for a start, to see whether it 
helps, after that you may want to use a batch renamer, there's some free 
ones around).
Also, in case this doesn't help, when have you been running some system 
maintainance tools for the last time? OSX is really bad in some terms, 
especially when it comes to things such as disk permissions (this hasn't 
changed for one bit with OSX.5 and the sub-updates). I cannot recommend 
Onyx too much, it's absolutely excellent for all these maintainance 
jobs, I just fixed a friends machine in about no time, it suffered from 
several issues pretty much related to what you experience right now 
(missing EXS and Ultrabeat patches, missing samples, weird error 
messages). Onyx is free:

In case you're scared of running it, I can almost assure you that it 
won't do any harm to your machine as long as you stick with the default 
settings. I've been using it sucessfully on some machines. Really one of 
the best system maintainance tools I ever used (including those for both 
OSX and Windows).

Good luck,
