Problem with <<Jaiorunerk's Diary>>

Hello ! First of all i'm sorry for my english and i hope your will understand what i am trying to say .
I started to make some question that will help me to expand my cube inventory .
So i started with <<The Legend of Vindachinerk>> quest ( you can find quest info on the internet , so i will not explain very detailed ) . After this quest i must do <<Jaiorunerk's Diary>> and here's come the problem . The quest it must end when i talk with Yiehmonerk but after i talk with him nothing happen . The quest remains , and when i press "J" it says that it's DONE but it's still there . So i think to click abandon and do the quest again and probably will work , but after i press the abandon button i can't do the quest again . So what should i do next ? I really want to expand my cube to maximum level but i can't if i am not doing this quest . I want to mention that after that quest is done , i should do another quest , so i tried to do it ( <<Where's Vindachinerk >> ) but i can't because first of all i need to do that one (<<Jaiorunerk's Diary>>) .
So what i can do ?
