Well, I made a mistake and black screened my MK3 by trying to update it with a mode 1 V32 disk. I now have a mode 2 V32 disk, but it won't take. From what I have read I now need to downgrade it to an older firmware. I'm looking for the V18 firmware because that is what originally came on the unit based on my build date. Any help would be greatly appreciated. I just installed my Intravee setup last night as well, and I'm eager to use it.
