Error message while adding index words on wrong connections?

Hey again,

first I had problems with the HTML compiler - I moved now all my projects to C:, now it compiles.

First problem now was, that the index wasn´t build up. Means, I had the index file, but the connections/relations were not made. I´ve reconnected every theme with the corresponding index term, that is finished and works properly.

Second problem now is the following error, displayed while I try to reconnect index terms in the folder of the "incorrect connections". I have no clue, why there are any, but however, when I try to reconnect just the second term, the whole application shuts down!

(Sorry, it is in German)

Does anyone have a clue?

I read something about having problems after updating to 8.0.2, which I already did. Maybe it results from this?

Thx so far
