Hi Pete,
Finally retired and now have time for flight sim.
When I just re installed my FSUIPC4 version 4.53, which has been "parked" for a few years now, It took several minutes before FS came up. Seems all happy there now, as subsequent boot of FS takes a short time. However, when I go into my PMDG a/c, the FSUIPC4 module notes it is unregistered and not fully functional, but it did allow me to register it(I still have the key and order No etc). I have security turned off. I think I read somewhere, you no longer support early versions, such as mine.
I wondered if this was the time to upgrade to your latest version, including Wide FS7? I presume because my version so old, I start again with no upgrade?
Regards
Geoff
