Then I would look at the Forms 'digimain' and 'main' and ensure that all objects on the form are defined properly and their source is valid. There are some tools here that allow you to open a form like a table and see the class info on each object on the form. It will take a little investigation on your part, but you may just see something wrong with an object on the form or the parent class that object is pointing to.

Best I can do..HTH
