I would go ahead and call 'em, man. Although I'm new to this NFA game as well, as you can see on the previous page my checks took only a week and a half to get cashed, and I sent my 3 forms off only a few DAYS before you did.
That's my 2 cents brother. I'd call 'em and politely ask what's up. It couldn't hurt anything.
Good luck bro,
