Nostalrius Begins - Quality wow vanilla realm (1.12)

I am having issue with my Damagemeter addon, it is not tracking the damage/dps of certain classes(mages, warlocks, hunters). It was working perfectly fine when I first downloaded it a while back.

As you can see from the image in this link, the mage in my group shows that he is doing 0 damage/dps.

Does anyone else have this issue or know how to fix it?

You should use SWstats instead since it syncs with everyone else in the raid. It is what people who upload to realmplayers.com use.

I am using both actually. I use damagemeter to track current fights since I havn't figure out how to make one of swstats tabs track only current fights instead of overall raid stats.
