If I had FOC installed on two computers and played it online using both, is there a possibiitly of my key code being deactivated?

I'm wondering if this could be the cause of my inability toplay online over the ast few days; every time I try I get a (different each time) errorr message.

EDIT: It wasn't that, thanks anyway though.

Yes, it's possible, though I find it unlikely. I mean a single key on two computers seems a bit small to blacklist. You can always contact Petro and ask them about this.
