Cubase 8.5 transit vst not working

It downloads VST Transit the first time I run it after starting Cubase, subsequent times it runs the downloaded version until Cubase is restarted. The download seems to work fine and then VST Tranist is started. It always runs version 1.0.0, and no, neither entering, or copy pasting an @ sign is possible. (Copy-pasting simply removes the @ and entering an @ has no effect on the content of the input box.)

I have not touched the installation, merely upgraded from 8 to 8.5. The installation was done with all the default options.
