Hey Guys,
First of all, the Beta Patch is essential for on.ine play.
It fixes some major issues, perhaps the largest but being the pre-patched ability to follow cloaked ships, using the "follow target" feature in your navigation controls.
The most fun to be found online is definately with MODed servers.
TNZ is amazing and gives you Gorns Dominion Cardassians Maquis, just to name a few. It's well supported with dedicated admin. TNZ MOD should work with your machine, so if it doesn't, the answer most probably lies with "your machine" rather than the MOD.
DOMINION WARS is amazing and gives you even more ships and races.
All you need to play any of these MODs and still be able to play "normally" is to create a copy of your Assets file and title it "Assetsorig".
Then, download and run the MOD of your choice, and just switch the Assets file for the Original when you want to go back to normal. Take care, if you load a second MOD, that you load it over an "original version" of the Assets folder.
The reason so many people play the MODs instead of just the "normal version" is that these MODed games give you what we expected in the first place: i.e. more ships, more races, more fun.
I would be happy for anyone having trouble loading a MOD to give me a shout through the message system here.
If I can't help you myself, I'm sure I know someone who can.
Hope to see you online.
