saving my PT database

[unlucky513]

I put my old hard drive into my new computer to get some files from it to the new computer. I tried copying over the ptrack.mdb file and I keep getting the "file is in use/write protected" error... Poker tracker is not open, nor is any other poker-related programs. I've tried restarting and moving it, no luck. I tried burning the file onto a CD, and the file will write to the CD but the size of the file is 0 bytes...

What do I need to do to move/copy this file?
