Can anyone help me with the following problem which has occured recently?On stating FS9 I get a message that FS9 is unable to load some aircraft or software. It than shows that it was unable to load PMDGOptions.DLL. This means that although I can still use FS9, I cannot use the PMDG aircraft as the gauges will not load.This happened at about the same time that I installed and registered FSUIPC V.3.75, however, Peter Dowson assured me that it is nothing to do with FSUIPC. I now have FSUIPC V.3.80 installed but still the problem persists, I have even installed my old V. 3.4 from my back-up drive but I still have the same message.Is there anything that I am missing, or can do? I would be most obliged if anyone can help.Best regardsJohn Cattell

Are you sure the pmdgoptions.dll in in the modules folder?

Thanks for your reply, yes the PMDGOptions is in the correct file.

Try PMDG forum - they could have a FAQ's
