Actually, I also downloaded it a second time and it did not fix the problem. However, I am now up and running again.
If you follow the instructions above, you will be able to see the default folder that offers the files that you can chose from. MAke a folder in that area (on your PC) and then choose that particular one. It will not be the original, but you can also make different folders for different genres, ect.
Hope that his helps.
