If you try to create a new project and get the “Not a valid file name” message, try to create a favorite library and get the “Invalid library name,” or open a library and get the “No library files found” message, even when typing in a filename you know is valid, this usually means that EQ8 can no longer find your My EQ8 directory for some reason. Please uninstall and reinstall the program so that EQ8 can locate your My EQ8 directory.
