Hi, What I presented in the video is just one of the potential issues with EndNote. There are many others. Since I am not a technical expert myself, I recommend Googling to find out about other issues or contacting your institution's or organisation's technical support for further assistance.
it looks like it worked with everyone except me. I do get a pop up which says EndNote Error every time I fighter update citation or turning on instant formating. Does anyone has an idea what could I do?
Surely, it depends on what Endnote says the error was. But in general, restarting the computer may be needed. Also, I would close the library and document, and try to re-open them again. Lastly, look out for other factors that cause the issues.
