Cosmos Browser cannot register the host application

[_Toby_]

hi,

Since today, when starting the Cosmos Browser in C4D, I get the following error message:
Cosmos Browser cannot register the host application.

I already saw in a forum post that one should check the access rights. I’ve done all of that already. Does anyone have any further ideas?

Also, since today the 'Material' category is missing in the Cosmos Browser as well. I think there could be a connection…
