I have this kit and was confused about the DOSbox install, as well. Contacted the seller and found out I was supposed to run the main .exe program by right-clicking and selecting "run as administrator". Even though my user account was already the administrator account on the PC, I had to "run as administrator" anyway in order for it to work right. Of course I was only using it to move adf's from my PC to my Amiga, not the other way around, and no idea what would happen if you unplug that cable with it turned on... but maybe this helps a little?
