Hi Mike.
When you say that all the Vstep Servers are unavailable, is that excepting all of the ones that work?
After reading your post, I went and checked. Got onto the Solent, Rotterdam, New York and Hamburg (ordinary) environments with no problems. Then went onto the Solent Add-on environment. Again, no problems, logged on rapidly. No-one on any of them, granted.
Lost interest after that.
I'm on the Solent Add-on one right now.
The problem might not be with Vstep in this case....
