Alone in VoA

Hey there... I'm new to raiding and WoW.... I just tried to go on a raid with other people to VoA...but when I entered I was alone in the raid. I tried to reload I left the raid to reset all instances...then I got back in the raid...still alone. Tried restarting the game...same thing :\
I'm on Ragnaros btw.

you're already locked into a different Voa raid id. you'll have to wait for the raid lockouts to reset.
