Hello, I bought endnote today and have found it to be unusably slow on my MacBook air 2017 os 10.15.6 . I have updated my java and yet still it freezes even when copying references to my library. I just want to refund this, but its not working using the request form here: support.clarivate.com/Endnote/s/RefundRequest?language=en_US , due to the case not being valid…
Error message when trying to refund : Review the errors on this page. Case is not valid
Why is the case not valid? I would really appreciate any guidance on this issue.
