Numpty question re:GTR

[dougc]

Afternoon all, I'm after a bit of advice regarding GTR. I've been playing the standard game for a while and I have started sniffing around for updates, new tracks and the like. I have downloaded Brands Hatch but I have no clue what an .rar file is what I need to do with it to get it into the game.

HELP!!!

Aha - it works! Well, it worked about an hour ago actually and then I got distracted by the Brands GP circuit

Thanks
