3.2.9 is apparently when it was updated for 6.60, but its all over google, so I think you've found it already, but macrofire isn't working anyway. In that case, maybe there's something wrong with your other plugins. Have you tried disabling any of them to see if one might be causing whatever problems you're having? I use macrofire myself, but when I try to set it up with pergame to make it load specifically with certain games, no games work at all, and I just get a black screen.
If you just want to try another alternative, cwcheat also has a remapping function built in.
