Trados 2021 sr1 cu5 killed wordserver compatibility package and nothing works now

Anybody knows how to fix this?   After updating to Trados 2021 SR1 CU5 I was not able to import some files.  I re-installed trados and now I cannot import anything.

When I go to install plug ins

When I go to install Wordserver Compatibility pack or Trados Compatibility and Migration pack. There is nothing there to be installed and I cannot open any file anymore
