Thank you! I fixed my bib-file (it did miss a year!), so that was certainly good advice. I also downloaded some additional packages through Miktex and tried out some other citation styles. Some of them work (such as apalike or plain), but the ones I would need don't.
The citation styles that don't work all give me a lot of error messages saying "Undefined control sequence." and the error descriptions look something like this (this one came when I used the style chicago): " ...r{Aiginger}{Aiginger}{2007}]{Aiginger.2007} The control sequence at the end of the top line of your error message was never \def'ed. If you have misspelled it (e.g., `\hobx'), type `I' and the correct spelling (e.g., `I\hbox'). Otherwise just continue, and I'll forget about whatever was undefined." I do not know why the name of the author (Aiginger) is repeated so often, that is not the case in my bib-file. In other error messages, symbols like % suddenly appear in the text where there are non in the bibtex file. Does anybody know what the problem might be? I tried different encodings when I exported my references from citavi to bibtex (UTF-8, US-ASCII, Western European (ISO), ...) but nothing changed. Is there a specific encoding I should use?
