I am at a total loss here, I just did a re-format WinXP re-install, and after a full day of install, I installed my 737-600/700 (Only), and went to create a flight plan from KORD to KDEN, but when the aircraft loaded (pre-flighted ready to load navdata) and fly, I did not have any functions in the 2d PFD/MFD the only item clickable was the autobrake setting, am tired and frustrated, what have I done wrong, should I have installed the 800/900 version too, According to the manual rhe 600 installer is a standalone product, also other than this aircraft just the Level D 767 is the only other aftermarket installed. I cleaned the fs install, BUT the Level D runs just fine Pentium 4 1024mb sdram 2.2gproc, Nvidia 6600 vid :-jumpy :-hang

OK, seeing as NONE of the PMDG PRO's want to answer this question, I will tell you the problem, it is the FSUIPC.DLL, If you register this, your 737 stops working, I have the 3.72 version, and noticed on a fresh install of fsuipc (not registered) all was fine........BUT when I went to register OR re-register, BLINK out go the eye candy........ a tip for you PMDG, and you won't have so many ###### customers.......STOP TRYING TO MAKE SOMETHING GREATER THAN FS ITSELF, use the kiss principal like Flight1, and FSD, I thought the B1900 was a headache.....:-hang

I have no problem with a fully registered FSUIPC. On your reinstall, did it write over another version?3.75 is what I am currently using. Now, version 3.72 as I recall, did have some registration problems in certain situations.A good idea is to look at the short FSUIPC.log in your modules folder to find out what might be happening.

I also have absolutely no problems with the registered version of FSUIPC.
