Hoster 4.02 problems

[slingshot]

I have all updates for XP so that shouldn't have been the problem. All files were converted with no errors.
I messed with it for 2 hours at a show last night and it finally started working right. Checked it this morning and it still seems to be ok. Still don't understand why I had to rebuild the data base when the files were there when I first down loaded the 4.02 and it played them when it first opened. I guess I'll see what happens at tonights show. I pray there is know problems because it looks bad when you can't get your show started.
