Leftovers from Mojopac

I made the mistake of installing the free version of Mojopac on the flash drive that I use for PA. Didn't like it and removed the Mojopac files, but this didn't get rid of it completely.

I changed the volume label back, but "MojoPac" still shows beside the drive letter at the bottom of the PA launcher, and under MyComputer, but not on the DOS prompt. I reinstalled the PA suite over the old one but that didn't help.

Also, I have 200kB less free space on the flash drive than when I started. Looking at the files and folders on the flash drive I don't see anything that obviously belongs to MojoPac.

To get back to a clean PA installation do I have to do a reformat?
