[AccessD] Can't open form

Hey All
I have client and on her machine when she trys to open a form from the 
Main Menu she gets a "Can't Open Form" error message. Other forms work 
fine and the program works fine on other machines. I  have a 
COMDLG32.OCX active x control on the form. Before I go and get her to 
try to register the OCX (she has it in her System32 folder, it is just 
that I really don't like monkeying around with someone elses computer 
system), does this mean she could have a corrupt COMDLG32.OCX? Would 
anything else cause this error to occur?

Thanks
