Amplitube 4 wont launch anymore vst or standalone

2 issues possibly related to each other.
1 when i launch cubase im presented with the following screen which is not normal.
2 amplitube 4 wont launch in cubase anymore as a vst or even a standalone.

All was working well until suddenly it wasnt.
cubase le 11, amplitube 4 max, windows 10 all updated.
any ideas what could have happened?
Now when i launch cubase i have to pick an option and also amplitube 4 wont launch in vst, just get this error message.


If it doesn’t work even as stand alone, get in contact with IK Multimedia, please.

I would try to reinstall the plug-in and make sure the latest update has been installed.
