>Night before last The Network Managers removed volume 3 & Volume 4 from our network and replaced them with a Large Volume 2. I can't get my app to run. I get a FILE ACCESS DENIED message when I compile the app. I have changed my MAIN program to point to the correct mappings, checked the Screens(Forms), removed and re-added the DE, removed and re-added the DB container, also removed and re-addded Grids. I can't find, what this message could be resulting from. Can someone point me to where I can look to for the solution. The USERS are waiting for the database to go back on-line. (PS I now realize that I need to learn how to develope the project regardless of the network environment) Thank you in advance for your help!

The safest way is to develop on local drive. What if you will move project stuff there and try to recompile?
Another good practice, actually necessity, is to 'develop on tree', i.e. project file is located in root folder and all project-related files (forms, libraries etc.) are located in subfolders.
