iam not sure about your vista problem, but it should work, if not, look around, and you'll find useful pages to fix your problem. (on epvp,2moons/dekaronEU homepage) just look around...
and youre looking for a 100x server or higher?
there are two servers i think...a 100x server and a 150x server..but the ms it very high i think...if i were you, i would go to a 30x server, thats enough. even 10x it very high and you would lvl fast(there is no working 10x server , just an example )
