My 737NG gauges are missing from the panels. I am using FS9 with the update and the 737NG with it's update and FSUIPC v3.41; also tried FSUIPC 3.30; but gauges still missing.When I tried to check the panel.cfg's using FSPS I get an error saying FSUIPC v2.90 or later is required. Anyone know what could be wrong?

Did you install any PSS add-ons lately? I remember PSS having a problem with the registration file for FSUIPC. Try to rename or move your FSUIPC.KEY file from the folrder modules and try again. You might need to re-register if you are using a registered version of FSUIPC.Hope it helps,

Many thanks Mats Johansson!!!You solved my problem.I had re-installed PSS A320 Pro; I guess this was the culprit.
