Command Button Wizard error message

When I try to use the wizard to put a command button on a form I get this
error message:

Error accessing file. Netword connection may have been lost.

It then wants to send an error report to Microsoft and shutsdown Access. I
have try everything to correct this problem and I need desperately to use
this function. I have created macros to go around this problem, but I get
the same results.

Any help would be appreciated.

I am running MS Access 2003 and had a trial version of 2007 that will do the
same thing.

I run windows XP and have 1GB of RAM.
