Still waiting to get some sort of response from dkpsystems. Any idea what this might be? Until we figure it out we are not able to use the mod to see peoples dkp.
The output seems to be giving me the proper response.
I've looked at your site and I see the problem. It seems that you still have item snapshots that haven't been purged. Every time, you re-open the game, if you choose to "keep" the item information, it re-applies the recorded point totals.
In your case, Slyssta received Pauldrons of the forgotten vanquisher for 125 points on Aug 30th. When you chosoe to "keep" the snapshots, it takes his 17.5 points, and subtracts 125 points, leaving you with -107.5.
If the data for that raid has been uploaded (which, since the item is on the site, I'm assuming it's good to go), choose the "Purge" option when opening WoW (or just type /grss reset and then /console reloadui) and you'll see your data show normally.
