skill poison 0/375

Hello,

I have a bug on my rogue poison quest at lvl 20 so i leave it to take again.
But NPC fizzule or shenthul don't give me the quest again.
I have try delete the cache folder, download other burning crusade game.
I have try everything with NPC for they give me the quest again but no succes.
i have create new rogue on x5 outland and do the quest, it's work but on medihv i have deleted for take again, great error.

I have waiting 2 month but bugtracker don't help me because i'm the only one with this probleme.
The game master don"t help me they just said me all time "try delete cache folder" so it's useless or wait bug tracker but with 1 priority
and chain quest working it's never fixed!

So only game master octantis have the mind to help me. He said me create a resquest when i'm logged on.
But i'm waiting 5-6 days for having an aswer, i can't be connected 24/24 so he all time answer me when i'm disconected.

I'm a rogue lvl 70 without poison, i'm useless i can't pve, raid or pvp.

My character is totaly locked.

Please someone help me .
