iTunes match crashing at step 3. Win7 x64 iTunes v10.6.3.25
I'm having the same problem as so many other people it seems - part of my library is matched and now I'm stuck with a constantly-crashing iTunes when it gets to step 3. I've checked for zero-length files or tracks where the track length is invalid - all clear. Checked for tracks that have their match status showing as 'error' - don't have any of those. I've really come to a dead end here - any other tips or advice?
I spent a while using sysinternals process monitor to see if I could find the source of the problem and it was always tripping up on a certain track recently ripped from CD (using iTunes). So I deleted that track and it crashed again but on a different track. After a while it became clear that it was all my long tracks that are causing the problem - and I have several hundred tracks that are over an hour long - DJ mixes, mix albums, stuff like that. Given that I'm not going to delete all these tracks (as I don't have sources to many of them any more) just to get iTunes match to work, is there any way I can flag these ones as "don't match" so they get skipped? Or any way I can take the remaining short tracks and force iTunes to manually match those?
Or am I just S.O.L until Apple admit there's a problem with very long tracks, and try to fix it?
