Can't find publications anymore using the DOI - tried several reinstallations
I am writing a review paper and therefor need to include hundreds of publications into a citavi file. Everything worked perfectly throughout the last years, I am simply using citavi to grab a title by entering the DOI. It literally stopped working today, I already tried severall un- and reinstallations but could not figure out why it stopped working. I was working with citavi 6.8, then installed 6.11. and then went back to 6.7, however without any success.
Can someone help me, it is really necessary.
