thanks for posting this... I've seen quite a few complaints about the DLC export key being corrupt, but it looks like you hit the root of the problem.
I have no trouble playing WT DLC in GH5 now, but I also don't have either of the 2 tracks in question.
The export key isn't corrupt like you are describing it but it does make the loading time atrocious whenever you load a music track it will load then when the animation for the loading is done it will spin a ring in the bottom right corner until it loads then when you get to the song and drum a bit in the beginning it will spin that ring again and then it will catch up and you will be in the middle of the song failing it
I'm not gonna delete the export code because it costed money but ill will just have to hope that Sony comes out with a firmware update that fixes this problem
Has this issue been resolved? Is it now safe to download these songs? Thanks!
Ok I had the same problem, i download a bunch of GH5 songs GH:WT songs and I also have the GH:WT patch, ok, first it was megadeth pack and disturbed pack, it worked fine, but then i downloaded more and i got a message saying, data damaged or corrupted no DLC can be used. But i didnt download banjos nor eric johnsons song, so what is going on?
