I play the German version, first of all I apologize for my possible bad grammar and incorrect spelling!

Here is my problem:

First I finished "Rumors of Ledecestre"...
Then I started "Walls of Tempelbrough"
Once I delivered Aethelswith to the camp next to the river, a cutscene triggered...
Then "Tilting the Balance" started... after the cutscene with Lady Aethelswith in Tamewreothe, nothing happened...
I had to quit the game and a day later, I played about 14 hours some other quests (Lunden, Asgard etc.) and now the quest says i should meet Sigurd and Uppa in Tempelbrough!?!
Is there something i can fix??? Restart or something???

There are no questmarkers... I went to "Offechirch" after I read a walkthrough... nothing...
