Hm, I think I ran into another bug,m and this one threatens to stop the main quest. I met Delphine, went to Kyneshain, killed that dragon there, she told be she belonged to the Blades (? = Klingen)and that I should meet her in Riverwood (? Flußwald in German). I am, I slept in the Inn, I visited the hidden room, I talked to her, but nothing happens, she offers the same options for talking, I could ask her who the Thalmor are and why it is important whether or not I am a Dragonborn. She does not enter the basement hidden room, but stays in the tavern. Nothing else.

Have no clue what to do now, there is no quest continuing, I mean no main quest, only side quests. Googling tells me that I will infiltrate some embassy next, and that Delfine would instruct me. But she doesn't.
