Did you install your SQL patch and the GeoIP.dat file? That could be a problem.

I didn't need to do any tweaking to any files of supertracker and I'm running a fresh install of 1.3.9h, except for some template and side box installs; everything is running perfect.

I've used Supertracker about a year ago, and never installed GeoIP.dat before. I don't know what its for, but I installed it anyways. It seemed to work without it just fine...

I downloaded the supertracker mod today and installed it today. no further tweaks or mods needed for 1.3.9h. as far as I can see.
