So I had bought endless dungeon last wish edition about 6 months ago. I have been trying to listen to the soundtrack since then but every time I try to launch it, it gives me an error and does not launch. Tried on 2 computers and nothing still. 

I have talked to epic games support and they said "it seems that the issue is within the game files (soundtrack prior) which causing for the game to crash and received the error code/message."

The error code is LS-0013
