I downloaded and installed the new FSUIPC 3.12 (unregistered).My PMDG 737 PFD/ND/EICAS screens no longer work and the standby altimeter has a "gyro" flag on it.My PSS A330 panel now shows 4 engines instead if 2.Going back to 3.11CheersSimon

What did Peter Dowson say when you reported this to him - you have contacted him, haven't you ??David

Posted it on the FSUIPC board @ simflight.comDon't have/can't find his e-mail address.Simon

I have the registered version of 3.12 and don't seem to have those problems with my PMDG 737 or My PSS A330. Your post sure made me go look and see if I'd have the same trouble for myself. Will

Interesting - maybe its restricted to just the unregistered version then?Simon

SimonI have the PMDG 737 and am a registered user of FSUIPC and I confirm that everything works fine as before with the new version of the dll. I suggest you make sure you have power to the instruments. Confirm please battery and external power/apu is on and engaged.RegardsTimhttp://www.spottedantelope.com/bwomack/ima...aam-sim_sig.gif

I have the registered version Simon so cannot comment on how the unregistered version works but just a thought.Do you/have you re-registered the PMDG and PSS aircraft in FSUIPC?I'm not sure if you have to re-register or whether the registration carries over, just a thought.
