JenovaXP,
Since your savegame is loading MXM, I assume it is mine.
The 100 soundtrack error, besides being cause by having an existing soundtrack 1, is cause by the wrong dash version.
What dash version do you have? I am assuming it is not 4920. If it is lower, you need to update your dash, if higher, you need to downgrade your dash.
I also notice that you never posted that you were having any problems in my thread. So I didn't know you needed help. Oh and BTW, instructions to upgrade and downgrade are in my thread and FAQ.
One last thing... Buy the game. You will always want a backdoor into the system when softmodding. To skip this is playing with fire, and you WILL eventually get burned.
Morden.
