Your problem has nothing to do with the firmware key.
Something has happened to your installation of Isaac; please email firstname.lastname@example.org
I have had a similar lab view error for over a year. It just means that the graphs initially draw incorrectly. I sent a request in way back but nothing. I also reloaded all software but still there. I have Isaac ver 4.0.0 the error text is related to lab view "Error 1077 occurred at Property Node (arg 3) in MSGT scale y axes.vi->iBike calculate and scale Y axes.vi->iBike top-level VI.vi". So it may be a bit different but still annoying since it means the plots do not auto scale properly.
So there are some odd Lab view implementation bugs out here.
