try enabling the MainTank Frames, perhaps? We have more probs with CT users not getting Mts, never had a prob with oRA. And if the MTs were set before you joined raid and perhaps you didn't get a proper sync, hit the "request status" button
It's enabled, but i see no frames. But I also have issues with perfectraid frames not always updating and sometimes the fubar ammo thing, so maybe it's all part of a bigger problem *sniffs* Would it be safe to delete all under \addons (keeping settings) and reinstalling all addons?
