DeepL doesn't work after new install of Trados Studio 2021 SR2

Hi everyone, I just installed Trados Studio 2021 SR2 on a brand new computer and tried to install the DeepL plugin. Now, I get the message that Studio needs to be updated because the plugin is not compatible with this version. Of course I looked for an update immediately but I am on the most recent version I can get. And everything worked fine on my old computer two days ago. So, I took a look at the change log of the plugin, which was updated yesterday. Can anyone help or point me in to the right direction?
Thanks for any help.
