Having the motherboard changed would almost certainly cause this kind of issue. Not just with this but I am sure other things you used to do will be effected too and may need to be reloaded.

For a computer person the fix would be relatively easy. They would just get on the internet and download whatever decoder was needed. The best thing to do is get a friend who is into computers to take a look, it should not be hard for them to fix. If that’s not possible, you may want to call or go to the place that did the motherboard work and see if they will help you out. Since you already paid them they may be willing to help.

Some decoders cost money and some don't. Someone into computers should be able to download a decoder for free.

I hope this was helpful.
