Whenever I try to sync and add more songs onto my iPhone from iTunes, I get the message "cannot be synced; The required disk cannot be found.

It also says it timed out. Any suggestions?

I'm 1.1.4 and I used iPlus to upgrade, plus my YouTube is still out. I researched the YouTube thing, no luck.

Thanks in advance

If I were you I would uninstall iTunes and reinstall the latest version. This should hopefully sort you out. If it does not, we'll have to think of something else

You're a genius Doktaphex! That did the trick. Thanks for the response and thanks for the help, Doks!
