Form Instantiaing Error

Guys,

I had a recent computer crash that seems to have wrecked some havoc in my Visual Foxpro 9.2 system.   The first problem was that I could not open sections of Foxpro.  I solved this by reinstalling Visual Foxpro, but the second was far more incidious.  

I found that I would open forms and they were stating that some Class libraries not found.  I always backup, so I restored the entire directory from my backup.  No good.  So that is not a solution.

The error occurs in this fashion.  I open a form (most of the forms are based on a couple of classes), erroring during the load with "Error instantiating class.  Cannot find r:\source code i-servicing\inservicing\g3\class\aco\aco.vcx.

There is a DIRECTORY r:\source code i-servicing\iservicing\g3\aco but ACO.VCX was moved to r:\source code i-servicing\g3\class\aco years ago.  Why the revert?  What is worst is I cannot save the new directory location, even though when I select the correct path for one form it does it for all forms.   But, saving the form does not save the new path.  If I restart Foxpro I have to do the whole dang thing again.

And, when I go to compile the forms I get an error: File r:\source code i-servicing\g3\class\aco\aco.vcx is in use and cannot be recompiled.

What worst, is now I am getting a set of errors in my code after compiling.  A typical example is:

laHolidays[1] = {09/01/01}      
Error in line 676 of frmCLIENT.rawachmicrodeposits (record 77): Ambiguous date/datetime constant. Use the format:
  {^yyyy-mm-dd[,][hh[:mm[:ss]] [a|p]]}

So, anybody got an idea what the heck is going on?
