And then the Backup starts, uses 100% CPU load on only 4 cores (top level coders!!!), it keeps syncing for entire night and after 8 hours, no progress at all, so the "No" on sync seems to work as perfect!
In the course of your troubleshooting to date, have you worked through the following document? (You're reporting several symptoms consistent with a LSP problem.)
I had to uninstall my NOD 32 Antivirus Software to get it to work.
As I have mention in another task here at the forum, I will never buy a IPod/IPad from Apple again. For over 1,5 years there has been a lot of problems with your crappy software (I never get any information from the software why its failing for example), playlist disapperaing, music from my HD removed, sync problems, play problems.
It's sadly to say one of the worst examples of "professional software" I have every used.
