WotLK Every time i get to a bg i get a wow error

[N3FA]

Hello guys and thank you for your time!
So I have a problem with my wow client only in Blackrock s5 bracket BGs!
Every time I join a BG I get the classic wow error and my game closes......after I reopen the client I log in to character normally (no character already exists notes, nothing strange) and i am inside the BG with a deserter timer!
I tried to get Large Address Aware and I used it on wow client as I was told.....nothing changed!
As i said i play many years in Icecrown realm and in frostmourne realm and i never had this problem.......I run old client and i have entered the same Addons and CATA models with patches as in other realms that work fine!

does it happen when you join opposite team? in that case you may disable "mercenary mode" as workaround

When i get the other faction i get the error message is that normal?

[skullatbash]

it is not "normal" but you are not the first one who face this issue.

Are you playing with "standard" client or the one with WoD/HD models?

Its old client but i've dropped the models (patches) inside myself......no problem in other realms nowhere
