Activation Adobe Acrobat DC

Hello community,

I have problem with my Adobe Acrobat DC Software. I could activate it in two computers and now after reinstalling it on my updated OS it says I have already two activated devices. The computer where I had it installed does not exist anymore. So I cannot logout from that device. Do you have any recommendations how to get the software running again. The Adobe support said they can't do anything. Perhaps somebody in the forum can help me.

Best wishes

Simon
