itunes for Win7x64 aborts in Step 3 while Match is uploading to iCloud
I'm running iTunes 11.0.4.4 on Windows 7 Ultimate x64 SP1 (build 7601) with an Intel Core i7 and 12GB RAM. I just signed up for iTunes Match today and I'm trying to upload my music (8,913 songs) into iCloud. I've run Match, multiple times, and everytime I get to Step 3, it terminates with an application error. I've gotten my music library partially loaded (~7,600 songs), but I can't get teh final 1,300 or so to upload.
I tried installing iTunes again. I've rebooted. I've terminated all other non-essential programs. I've even started iTunes in Safe Mode, but each time I get to the point that iTunes starts to upload these remaining songs to iCloud, I get a generic EventID 1000 application error.
Does anyone have any suggestions on how to proceed to resolve this?
Thanks, TimD.mn
