the monkey of the archcanon wont give me the key he jst acts like normal and i have tried talking to him heaps of times, he jst wont give me it!!! i dont want to kill him either coz vivec is to solid to fight, why shud i do!?!?!?

No, you don't have to solve the puzzle cannal. did you really speak to the archcanon? he's in a room where the door is locked and you'll need the key to unlock it from a guy just outside his door.

i went round the back, i tried every speech option but he doesnt say much, i ask about the temple and vivec he still doesnt give me the key any ideas what to do??

it def is the archcanon as well coz i killed him once and he has the key on his body

You have missed a quest or part of a quest needed befor he will give you the key. Go over everything you have done and then check your walk-thru to find out what step you missed or what part of the quest is still needed to be completed. It sounds like you may only have one more think left But, I can't remember what it is. But I'm working on it for you.

Have you completed all of the forth trial and had each one of the three Ashlander camps recoginize you as the Nerevarine? Then visit all three of the Great houses and had them pronounce you Hortator. befor going to Vivic talk to the Archcannon.
You didn't sell or leave any of the artifacts you collected during the seven trials anyplace? you need all of then on you when you talk to the Girl in the tunnel and when you talk to the Archcanon or they will not reconise you as Nerevarine and you wont get you final orders from The God Vivic.

Do you remember what the artifacts were? i might of sold them, i have completed trial 4 because it says so in my journal

Artifacts needed:
1.The Dagoth Cup and the Shadow shield from third trial
2.the Moon and Star ring from the forth trial.
3. the Amulet (Madstone) given to you after escorting Sinnammu to a safe shrine that you cleared out for her.
4. The Magical Thong given you by Ashkhan after you bring him a bride.
5.The Erabenimun Tribe gave you an Enchanted symbol(Seizing of Erabenimsun)
6.The Ring of the Hortator and a sealed package was given to you when the House Redoran named you Hortator both must be in your pack when you present yourself to Archcannon Saryoni in Vivec
7. The Belt of the Hortator given to you by House Hlaalu's
8. the robe of the Hortator given to you by House Telvanni.

Now with all this you can see the Archcannon and then be sent to meet Lord VIVEC, Good luck I hope this helps.
