I left an Access 2007 application open, and left my computer the next morning, the VBA module was corrupted. The message I get when I try to open the module, I get:
"The module name 'Module1' is misspelled or refers to a module that doesn't exist."
"If the invalid module name is in a macro, and Action Failed dialog box will display the macro name and the macro's arguments after you click OK. Open the Macro window, and enter the correct module name."
