Yes, my computer is about 7-8 years old (2003-2004) and wasn't expensive when I got it, so it wouldn't surprise me that things are low-end. I'm running Windows XP with 1 gig ram, AMD Athalon 3000+ 2.0 GHZ, 15 GB free space out of 75 total.
If my computer just isn't compatible I understand, I'll just have to come back once my computer is upgraded.

I'm saving up for a new one right now.
