First I did 5 extra jobs for both Delvin and Vex in Winterhold, Solitude, Markarth and in whiterun and I did the special jobs in that same order exept I coud not start the one for Whiterun. So I thought that mayby I have to do main quest of the thieves guild first in order to get the last special quest but Delvin wont give it to me not even after doing 10 nubers job for Delvin in whiterun and 10 bulgary jobs for Vex. I have alredy done the side quest for the fence concerning the khajit caravans and retrieved those journals to Vekel. Still nothing.. What shoud I do?
SORRY FOR MY BAD ENGLISH my excuse is that i'm from Finland.
