Sadly still not working on W2k 
Are you joking? windows 2000 in 2011? Ehi i have a copy of windows 3.1 somewhere, are you interested in it? 
The fact that the client doesn't work with w2k is a GOOD THING.
But seriously, why should I replace a perfectly running system that's working as a server? I'd need to buy new hardware, a new Windows, install and configure it along with all the tweaks and services running on top of it. Just to run the client of an experimental currency? Yeah, like that will happen.
As I said before, I provided a solution already and hope that the Devs will add it.
