Yes, it was the password reset URL (http://il2sturmovik.com/account/password/reset/) which is linked from the log-in page on the splash screen.
I just don't know why it was spamming it thousands* of times? I think it was directly under the 'Allow Access' button on the Firewall pop-up when I clicked it.
I'll boot it again shortly and see what happens...
OK i'm pleased to say it didn't happen again, woohoo! Thanks for your help anyway chaps, i'll be giving it a thorough testing tomorrow evening fingers crossed.
