Help with FSUIPC3->FSUIPC4

[cuui]

I'm following the advice on the download page...I haven't purchased anything besides FSUIPC3 yet. I downloaded FSUIPC4, it installed successfully, but wouldn't accept either checking old registrations or entering new registration + using my old key. I guess it's not supposed to...lol.

Support please email or respond to advise,

thanks.

You need to buy a new key for FSUIPC4 it's a completely rewritten program for FSX only. FSUIPC3 was for FS2004 and earlier editions of FS.
