Problem with mixdown

[jco1954]

I'm having a problem with the mixdown to file on Guitar Pro2. I know it's old, but I still use it. I'm trying to mix down to files on 1 of 5 songs. This one song is giving me fits! Each time I try to mix down a small box pops up saying mixdown aborted. Anyone have a suggestion? Thanks

Ok, I tried again but unplugged the USB Interface before I tried and it worked. I don't understand it, but I'll take it!
