Are you able to create new project ? If yes then your project file might have been corrupted. If no then this error has nothing to do with Visual BASIC internal error. This error has been thrown by Windows OS. This means that there is some problem with your
VB installation (there might be certain conflict of resources or other). Try using some registry cleaner program to clean your registry errors. If this doesn't help, then you have to reinstall
VB. (After uninstalling your
VB, make sure you clean your registry for any error and only then reinstall.)
Hope this might help to solve your problem.
