FMC is confused

[Guest Kilo Bravo]

I need help to reset my FMC in the PMDG 737-400. He does not know on what location he is. The location is stuck on N4715.5 E 011210 which is LOWI in Austria. I can program from here to any airport. On other locations he stays on LOWI location. On page 2 is the actuell location which cannot transfered to the airport on which I am .!! Have no explanation to this. Is ist possible to overinstall the disk so it will restore itself. I am not a computer wizzard. Who knows an solution ???:-zhelp

I do not use the INIT POS page, I believe it is just eye candy that would be used if there were an inertial navigation system. Rather, I start with the RTE page and enter the departure/arrival codes. From that point on, the FMC is "positioned" and works as expected. This applies to the 737 only, not the 747.
