Loading the file
If the file you have is in DCI/Nexus format, you must first convert it to a VMS with the DCI2VMS program. Then you will be able to load the file in FPDEdit. You can only load/edit Expansion Edit files, not the system data, rename files, etc.
To load a VMS file, from the main window click "File", then "Open Expansion Edit File". A file dialog box will open and you can choose the VMS file you wish to edit. If you try to open a non-compatible file you will get a message telling you so. If your file is a proper Expansion Edit VMS, you will be taken to the slots screen.
On the left side of the screen is the wrestler's data, on the right are the buttons that take you to the other parts of the editing process. The "Save" button at the bottom is the main wrestler save button, the one that saves the changes made to file (the others just save to memory).
When finished editing a wrestler slot click "Save" to save the previously saved-to-memory changes to the VMS file or "Cancel" discard all memory changes.
