Airport Register

[Buffalo9]

Hello;
I'm trying to register the airports in P3D but everytime I click on register, a window pops up and tells me to put P3D into windowed mode.
Strange this is, I already am in window mode. So, I try to switch to full then back to windowed but to no avail, the register window never opens up.
I've run P3D prior while registering the products and don't remember having this issue before.
I did, install the latest Nvidia driver last night, other than that I can't recall anything that's different this time around.

Thanks in advance for any ideas, not even sure if this is a FSDT or P3D problem.
Bob

If you use the Prepar3D Migration tool, you have to turn it off entirely, at least during the activation, because our add-ons are entirely compatible with P3D and that tool might interfere with this.

As an alternative, if you have FSX on the same system, you can just activate the scenery in FSX and you can do it even if the scenery is not installed in FSX.
