I worked through this, but have no idea what I did to get it to work. I flashed back to 3.0.3n and loaded a msq that was made with this firmware. I got the error posted above.
I then opened multiple msq files that were created with previous 3.0.3x firmware and it opened them up with no error.
I reopened a 3.0.3n and still got the error message.
I opened up the previous msq that worked, I believe it was a 3.0.3h and copied all my settings from a later msq screencap. I then saved it, opened it up, and it worked, no error message. I unplugged the power from my diypnp multiple times during this process to try and find the culprit.
Out of curiosity I wanted to see if this one would work if I reflashed 3.0.3r, and it works.
Earlier today I flashed back and forth between 3.0.3r and 3.0.3n multiple times trying to fix this. Full flash with jumper and without.
The only obvious difference from flashing now and from earlier is that my diypnp is not 25 degrees; it is now in the house.
Anyway, this has been a good waste of 4 hours
