recently on my hunter ive been trtying to do flexi but every time i get invited i get "you are queued for to many instances" and the inviter get " the player you have invited has declined the invite" and its instant,

now i know its only a problem with my hunter as i got invited to thok on my pala with no problems, i check my addons and i have no addons working on my hunter hat i dont have on any of my other toons.

any1 know why its auto delining invites for me and dose any1 else have a similar problem?
