■ You are attempting to run a program after unloading the main module or start-up file. Every program must have a start-up file so that Visual Basic knows where to start running the program. ■ Possible solutions: • Use the Load File command from the File menu to reload the main module. • Choose Set Start-up File from the Run menu to specify a currently loaded module as the start-up file. ■ If you need additional help, move the cursor to a keyword and press F1 to open the Help window.
