Its not bad firmware.
I can't comment on your older FB3 but for the newer one certainly the problem lies with the versions of the programmes you are now running.
I have Showrider, TraceIt, LiveQ, Draw3D all running on my system quite happily. The problem you're having is that the older versions of these programmes won't run on the updated firmware so you need newer versions from Pangolin. The same applies to Live Pro.
BTW from memory, QuickShow doesn't run on the updated firmware either. You need QS 2.
Unfortunately, I can't link you to where I downloaded my from as its not a public server, so you need to contact Pangolin.
