nw's Morgy if all else fails try a fresh install and start from scratch .. is the best way to learn how to effectively create a server .. and like most things becomes easier over time... months/years in-case of ut. As being 6-7 years old there's 1001 mods/mutators and gametypes to keep you occupied for the next 10 ten years
.
personally I love the Graphics of 2k4 out of all the series including ut3.. I dunno what it is but it's like surreal? on a descent GC that is (Graphics Card)
but of course it had its problems with veterans ... and myself as it dynamically was not as good as it's predecessor imo. for some reason Epic assumed
that we'd all like to feel like a 10 ton cyborg running through a swamp and ugly avatar's combined with silly voice-packs and weird gore effects. But hey someone liked this yeah?
personally I think ut99 is like Mohammad Ali's philosophy, 'Float like a butter-fly sting like a bee'
there were a few feeble attempts I might add add re-creating the ut99 game on the 2k4 engine.. but for matters un-be-known to myself at least they all packed up one day and closed shop.
there is an unfinished beta attempt in @ moddb though which I don;t think that Ive tested as yet.
good luck.
