Thanks.
Before I saw your message, I did finally figure out how to restore the library I had backed up on my old machine to my new machine. (The library is on an external hard disk.) I did a restore from the backup and plugged in the disk and everything was there. I had used the "safely remove hardware" feature to remove the disk from the first computer before I attached it to the new computer.
However, whenever I try and replace a field in the database on the new machine, I get an error that tells me that the file is locked. I have tried this with 2 or 3 files and gotten the same error, which is only different in the file name. Here's an example:
Media Center encountered errors while tagging and moving files. Check that the files exist, are not read-only,
and are not in use by other programs.
File locked: E:\Personal\Music\Aaliyah\Age Ain't Nothing But a Number\01 Intro.mp3
I have checked that the files exist (they clearly do, because I can play them in MC). I have checked that they are not read-only (by looking at their properties -- and the read-only box is NOT checked). I know they are not in use by other programs, since after this first occurred, I restarted the computer. Even after a restart, the problem persists.
I have no idea what's going on here. I have always been able to deal with a problem like this by restarting the computer, which resets all file locks.
Any suggestions?
