I hate to make my first post like this but I can't get any solutions for searching the net so I thought I would ask for some help here! Here's my issue-

-I'm using Vista
-Problem started after deleting a lot of files in preparation for the Touch.
-After connecting my iPod there seemed to be some slowing down and iTunes froze completely. Nothing changed on my iPod as far as I could tell the first few times.
-After disconnecting my iPod information would show up along with error messages such as file/folder not found. Messages like these showed up almost every time but eventually went away after trying to connect a few times.
-I tried many times to sync and see if I could fix it but iTunes would freeze and do nothing until I disconnected. After a few times some info on my iPod was gone (ie: Playlists)

I thought this was just an issue with my iPod and I decided it wasn't a big deal since I was getting a touch soon. However, today I went to test an old iPod on my laptop (also running vista) for fun and iTunes froze and didn't show any info on my iPod until after I disconnected. This laptop is new and has never had an iPod connected to it aside from getting my files off of one (before iTunes was even installed). I have no idea what to do and nothing I could find on other sites helped. I'm a bit nervous to upgrade my iTunes to the latest version before fixing this issue. Anyway, any help or suggestions would be greatly appreciated!

p.s- I copied my music onto my laptop using a program, it found a few corrupted audio files and didn't copy them. I'm not sure if this could indicate a larger problem or if it's a separate issue.
