Does the newly selected drive have enough room for the seq file?
(they can get big) .. maybe neither drive has enough room.

One option to free up some disk space:
RB creates a backup folder and makes a backup there when you make changes or save any files.

Look at your Realband backups folder and see if you can do some cleanup to free up some room.

Not sure if moving files would affect this at all, and there are settings to contain how many backups it keeps (in Options-Prefs). I have some drives where RB only has less than a gig of backups, but other drives have over 4 gig.
Thought I'd mention.

/The only reason I have multiple backup folders is because I manually made this happen, for most users there will be just one RBBackup folder located wherever you have Realband installed (likely C:).

Of course simply Emptying the Recycle Bin in Windows can regain lots of room on disks if not tended to regularly!
