While trying to use the new premium action for file transfer I get an error when saving the configuration claiming that a file or assembly _Rebex.FileTransfer_ cannot be found.
Continua CI version 1.9.1.481

Hmm, strange, for some reason the installer is not picking up some files it should be.
Try copying Rebex.\*.dll from the agent install folder into the Server folder (there should be 8 rebex). We’ll get another update out next week with the installer fixed.

Well, that produces a different error message (translated from German):
> The object of type “Continua.Stepping.ExpansionContext” cannot be converted to “Continua.Modules.Builds.API.Actions.IBuildSteppingContext”.

I’ve looked at the code and there is an invalid and redundant cast in the validation for that action. We will get that fixed on Monday.

Thanks for the quick fix.
Unfortunately I now encounter another problem: When I enter my hostname “[uweraabe.de](http://uweraabe.de)” I get an error like “The hostname could not be analyzed”.
How am I supposed to enter that hostname?

I’m not able to reproduce that here (I literally entered your hostname), and I can’t see that error message in our code. What protocol are you using?

My bad! I somehow managed to accidentally check “Use proxy” - sorry!
