Registration key won't work

[jetsmell]

I uninstalled, then reinstalled FSUIPC. My original was the paid version. My key won't work, what to do?

Pete Dowson is away until Wednesday.

Maybe you still have a backup of your previous "Microsoft Flight Simulator X\Modules\FSUIPC4.key"?

Alternatively you could login at https://secure.simmarket.com/ and lookup your registration details.

Why did you uninstall? If you deleted your settings and your KEY file then either restore them from your backup, or you'll need to re-register and re-establish all your settings. There's really never any need to uninstall.

If you've tried to re-register and your key isn't accepted you are making a mistake. As suggested above, find your full registration details and enter them exactly.
