Now I have so many DB's flying about, every time I attempt to load one it gives an error.
A general bit of advice for anyone experiencing similar issues:
-First, copy and save Fidel's mod package in a folder somewhere, such as My Games/FIFA Files/Fidel Files.
-Next, paste a copy of his mod package onto your desktop. Do all your work there, using the files from the desktop copy.
-Another helpful tip: copy Fidel's readme instructions and paste them to your desktop for easy quick reference when needed. Cut the DBM_ECI_T folder and paste it on the desktop as well.
-If for any reason the editing process gets you so mixed up that you don't know which db is which, DELETE all folders and files from your desktop. Then paste another copy of Fidel's mod package onto your desktop, and start all over again.
-And don't start by editing everything. Start by learning how the process works. Do some test edits until you figure out the process, and it's working correctly. After that, you're ready to start your editing project.
If you're creating test dbs for the purpose of learning how the process works, then it doesn't matter if you get the dbs mixed up. You can just delete them all and start all over again. For me, the quickest test is to edit all players to 1 agility. It takes 10 seconds to do in Excel, and it's easy to check in-game. Load the squad file, click on one player, and if he's not 1 agility then you know your edits didn't work and that the process you followed wasn't correct.
