Message I can't print cheque form

SUGGESTED

This message, "you have selected a Sage 50 Form file of another form type, or the Sage 50 Form file you selected has been damaged", is what I get on my screen every time I try to print a cheque.

I have tried recreating and saving the cheque form with no luck. 

Just before printing the cheques, I edited a direct deposit form. They are printing, no problem. But, ever since that edit that message pops up.

What else can I do?
