As starshard0 said, there is no way to currently use the online features of Docking Station, unfortunately. I was lucky enough to use the warp right around the last time it worked, and I want to say that was somewhere in the neighborhood of 2011/2012. So long ago! Having a username and password doesn't accomplish anything: It just gives you an error message about not being able to connect.
The only way to share Creatures offline is by exporting, sending/uploading the file somewhere, and then having someone else import that Creature. It's a rather long and manual process when compared with the Warp, although it's not too terrible if that's what you're aiming for!
I would recommend caution on the Gameware Europe site, because this was moved over from the old domain... Which is now owned by someone else, and can cause issues. If it helps any, I've created an entire list of safe links for all of the official pages, which can be found
here.
The offline patch is the only way to play Docking Station, at least for the moment. Good luck!
