Go to C:\Users\USERNAME\AppData\Local\Stardock\ObjectDockPlus, then copy the 4 files to the BU folder of your choice. I have different folders for different setups so all I do is unload OD, copy the 4 files from the BU folder back into the original folder, restart OD.
Hope this helps.
P.S. I am running 32 bit Win 7
