Shoot. I just saw the last few posts in this thread.
They had emailed me and told me I was missing some stuff in my sign-up info (namely, I put a line all the way across for phone number--hey, I'm not even going to be using it to buy/sell, why the heck should I put my phone # there). So, I just put in a fake #..but looks like I won't be getting it anyway.
I had Half-life, but sold it and got Q3..if I could get a free version though, I'd put it back on my computer Ah well..
