I haven't seen this happen for a long time, but it usually happens when my graphics card was overloaded. I suggest that you turn the display sliders down a bit to see if that stops it from being see through. ;-/

The only other time I have this happen, is with my Carenado HD addon aircraft. Reinstalling them fixes them every time.

Glad you got it fixed. I don't get that last part about the email address. Is it that you can't get an answer to a Support Ticket or something. When doing a full reinstall, that requires the entry to be removed from the windows registry, reinstalling asks for the email account which was used when the product was purchased (or the email account which has been changed to, by Captain Sim, at ones request), but nothing is sent to the email account itself in regards to installing.
The only things I know that get sent to the email address are the newsletters and Support Ticket responses.

If the problem is in regards to the Manual Offline Activation, you don't need to use a different computer or to get the key_xxxx.txt sent to an email address either. I always do a Manual Offline Activation now and I do it from this computer, which is connected to the internet and does have FSX installed on it.
