I have had an iPod for many years now and never had this problem up until now. I used to and still did up till this day add songs to my iPod from iTunes then delete them off my computer after having them uploaded. I have the setting checked "Manually Manage Songs and Video" which would allow me to add songs then delete them after uploading them. I have been doing that for years until tooday morning I guess? I haven't recently updated my ipod and songs last time I updated was I think end of last month and worked fine. I updated to 7.0.3. early today morning and tried uploading some more songs I had on my computer and it would not work. It just kept saying Updating Files on my ipod but never would sync them. I looked to check "on this ipod" to see if they had synced but it showed them greyed out with a circle showing it was still in the process. I also then noticed I had songs that had an exclamation mark and I did some research after that and people say it's cause the song can't be found. But I have been doing this for years..why did this happen now? Also is there a way to get iTunes to stop trying to search or locate songs..do you think that'd help my situation?
