Not Responding....can't open Files


When I try to open the program it will not open my accounting file. When I click on "File" a message comes up "File not responding". Task manager showing 30%CPU.

An error message had come up about a corrupt file previously. To get out of that message I clicked OK and the program appeared to work properly for that session. Since closing that session I have not been able to reopen files. (I run two company files).

Any help or advice would be appreciated....I don't know what to do!
