Help with Combo Box that closes my program

Hello, I just recently started programming with MFCs in visual C++ .NET

So I have this program where you select an item from a combo box and it saves it as a string, the problem is that when I call UpdateData(FALSE) my program shuts down... does anyone have any idea why this could be? Im sorry about being so vague but as I said I just started and dont really know how it works.

At this point, you know how it works way more than we do.

Attach the source file that contains the UpdateData() statement.

Its in the void CCRReaderGUIDlg::OnBnClickedConvert() method.
