Zurich registration issue

[Daantjeeuh]

I can't register Zurich Airport (P3D 3.4.14). I try to register my serial through the addon manager but I get an error saying I need to disable my virus scanner or something. Did that, to no avail. The online activation through esellerate won't work, I keep getting an 'Invalid Activation Set ID -25000' error. Any help would be much appreciated
