Sounds like a security issue. Microsoft recommends you don't run applications from the server as a security issue. If the copy the application to the local drive and run it there, does it work?

>The company just purchased and installed new Windows 8.1 machines. After making changes to a VFP form, saving gives the error message "Memo file \\server\formname.sct is missing or is invalid." Closing the form after that asks if I want to save changes. Selecting Yes gives me a 'VFP has stopped working' Windows error screen and a C5 error. Selecting No gives me a VFP window stating 'File is not open.', and refuses to close the window or VFP short of using Task Manager to kill the instance. Help?
