I posted a message here last nighthttp://forums.avsim.com/dcboard.php?az=sho...ic_id=7452#7469.... regarding the above error I get in FS whenever I attempt to load the PMDG B737NG. The error is in a box "PMDGOption", then once I move on to attempt to load the plane I bet "Your PMDG license is invalid or expired".I did get a key this morning from PMDG Registration(thanks). I see that I have to have the PMDG plane loaded in FS to register, however on loading the PMDG 73NG (after the above error mesages) I get the "Invalid Machine Code" error when attempting to access the registration pulldown. I can't get to the screen that accepts the registration key. Should I un-install the plane and start again with a fresh install? I'm apprehensive of making this issue worse than it is. I can assure PMDG that I have a legitimately purchased copy of the aircraft.I would appreciate knowing what the next step is that I should take to start enjoying this great aircraft.Thanks,Bruce.

Just to add the Rob has already contacted me by e-mail, and I expect that I will be flying with this bird soon. PMDG's support is great.Thanks,Bruce.
