Thank you for asking about the iTunes issue I was having, it actually was as simple as just setting my prefences from Data format to MP3 format. Which I felt kind of dumb about..
RE: Messenger. While I am IM'ing with someone, you can usaully send them or receive a file (like a picture) instead of having to go to email to send it. It will ask you if you will accept the file or not, once I hit accept it will error out & I cannot receive the file or try to transfer it. I use to be able to do it with windows, but I am now using a MAC. I can also send & receive a file while using Yahoo Messenger. I know, I can always use Yahoo messenger, but I'd like to figure out why it does not work with MSN Messenger, when it should.
