Led Blinky starting over?

[Propdept]

Ok I have led blinky. Before I got my control board set up for my game cab I set up led blinky. On a test board.
Now I have the control board in my cabinet and I have these problems
1. I have BERZERK in my game cabinet.  I decided to remove that rom and change it to BERZERK1. I can’t go into controls editor and set it up.  I used to be able to go into controls editor and pick the type of contrôler and specify the various buttons.  P1  colour blue keyboard button alt. P2 Color red keyboard button  shift etc....(I am just using this for example...  now I cannot in the lower left hand side of the controls editor do that. It is greyed out

2 I cannot add more games to my led blinky. When I do it saves it but it does nothing when I click on the game in hyper spin. 

Do I need to start all over again setting up all of my mame games.  Isn’t there a file. A CFG or INI FILE that I can just modify ?

Help
