I use WinRar. I use XP though.
If you're on either Vista or Windows 7, you need to enter an administrators password. If you're on XP, check to see if you aren't an "admin" and have restricted access.
If you're on Mac, I can't help you.
Woah, that soon? You work fast.
I've been thinking of getting either AA Havocs or upgraded DC lvl 4s. Can you pm me a price for 2 15" 4s with lvl 5 voice coils to 10509? I'm not in a rush.
