when running 2 hoster shows at once some files show corrupted

[kip777]

I have always ran 2 shows simultaneously, one for me and one for them and never had an issue ever until version 510.02. I used 5.08 I believe, with no problem for over a year. before that 4.32 and never had a problem. the reason I upgraded was for tempo and karaoke song purchase. anyway it only happens in my show which I have carried for many years and versions and computers. I know the files are good because I can search and play them on the new show. It is never the same songs, I can close my show and reopen it and the song will work. sometimes it will condemn a few songs in a row and then start playing the first good one it finds. now I did before the last show rebuild the database, didn't change a thing. my computer is up to date and has no operating system file issues. let me know what you think.
using version 520.02 now
