DM500 Manual Update Keys

[Monkey45x]

Hello, I have a dreambox dm500c and I'm using EvoCamD 2.12, and the channels have all messed up. The box knows that they're there, but they aren't working, the screen is just black, I need to know how to update it with the codes, I've tried doing the firmware but it's all the same.
HELP PLEASE!!!
Thanks

Have you tried re-scanning for all the channels ?
Worked for me when my 500C went tits up.
