Problem Syncing With iTunes iPhone 3G

Greetings,I am infact running Windows 7 Beta Build 7000, which is fully compatible with Windows Vista, so lets not start the whole BETA UNSUPPORTED trend.I believe, which may be untrue, that I am computer savvy...and this situation has me scratching my head.When syncing my iPhone, everything seems to go okay until the end. It seems all music files are synced properly, and I am noticing no issues with the phone. I suddenly get a nice message box...Attempting to copy to the disk eLements iPone failed. You do not have enough access priveleges for this operation. iTunes could not save to your music folder because you do not have write access. Check permissions on your Music Folder and folders in your Music Folder, then try copying the file again.First off. Im not sure if it means C:UsersTim HeckmanMusic or M:Music (The latter is where my actual MP3s are stored). Second, I have no idea what its trying to copy.Ive reset permissions on my user music folder, and I also reset permissions on my music folder inside of my M: drive...both yielded no results.I added music, last night, the same way I have for years now. The good ol click and drag, and never have I had this issue before.Now suddenly iTunes wants to go on a rampage and tell me that my computer is full of fail...I wish the error message was a bit more verbose. What file are you trying to copy iTunes, what directory do you want write access to...-sigh-Does anyone have any insight as I am starting to think about pulling my hair out...Thanks for the help,Tim Dell Dimension 8300 Other OS Windows 7
