Please, Please, Please help.

I had a form with the mscomm control on it. It was working fine. Today, I bring up the form to edit it, and it gives me an ole error and then deletes the control. So, I tried to add it back on. Everytime I try to add it back on, it gives me an ole error. It says that Appropriate license for this class not found. I have tried running foxreg, and it doesn't work. I have to get this done tonight. Please help.
