Targetin enemey/monsters with tab button doesnt work anymore

[TonyZ]

When I engage in PvP, I only choose target "players" In PvE, I target nearby objects and monsters.

Everything was functioning well until this evening, but now, when I use the tab key to target enemies, I get a message saying, "There is no target that matches the priority." Does anyone know what might be causing this?

In my case I can not target at all, right after the the starting the gameplay it let's me target soonest I get pass the first 2 mobs ( I guess the ones they show us on how to play) it stops targeting ;(
