i was tryign t odo online play today for the first time. in the options screen it said i needed to download the patch to be able t opaly because the level file isnt on my version. I was lokngon the website for patches but only found a 3.0 patch as the latest one. I have V3.50B2 should i update to the 3.0 patch? also do you losoe all your saved whiles when 'patching up' the game

You can't patch 3.50 to 3.0.

You would need THIS:
www.nanacide.com/wahelp

It has the latest patch.
Hope it helps! :)

does it override my existing files? should i back up?

http://www.nanacide.com/wahelp/installguide-original2.php? is that it?

always back up, it is common sense

Wait.

TTBOMK, the only version of the game that comes pre-patched to V3.50B2 is the TryMedia version.
If you bought the game from TryMedia, you can't use the latest Beta updates. You will need a CD version to use them.
