Can't enter random battleground at lower level...

Hey, I have a level 70 rogue with some honor heirlooms and I want to join random battlegrounds, but every time I queue it pops up and when I click 'Join battle' the screen just disappears and nothing happens. The queue icon at the minimap stays and when I right-click on it and press 'Enter Battle' also nothing happens... Any ideas on how to fix this and enter bg's?

Same thing is hapening with me. I'm 82lvl. although i did 1 randome bg some levels before 82... i did not notice what level i had. =/


Today i get level up and i get in to 1 randome again. Later i tryed again and did not worked again O.o weard..


now it worked again.... prob it's becouse of people in que ... if not enough it does not allow to enter...
