Captivate 2019 cannot login since Nov 2021

Hi,

Even though I have been using CP19 for many monthsin a row now for some reason, since yesterday it wants me to login and then says "update required" so it won´t start.

I have updated to IE 11 (which I never used and I doubt is still in use anyway as there is Microsoft Edge..) but that did not help.

Why is this happening?

Any tips?

Thank you!
