What is with 2.0b11? When I originally "up"-graded to 2b11 many songs suddenly became invalid so I had to fix some songs, other songs had no problems but were re-uploaded anyway and then they worked. When I went back to 1.03 to test it out and went BACK to 2b11, many songs are AGAIN invalid files. They were just fine before going to 1.03 - 2b11. Why does 2b11 think some songs are invalid when there was no problem before? Do I have to re-download all these files AGAIN?!
