I have a 0x32 MICS DR 4.1 S/W and a FastRad. I also have NRU 9.0. I can not complete a backup of my system. It inializes the Rad which is set at 19200, it accepts the password, and looks as if it is going to start backing up the software (small Flashing folder and KSU) on a screen) but then a message pops on that says internal error #81. Has anyone seen this before. I manage 65 different systems from 6x16 to MICS 5.0 and started backing them all up, and have ran into trouble when I started on this level, 4.1 sofware.
