I dont get how to download and merge with tremulous, i went to the site recommended (the only site i think) http://tremulous.tjw.org/backport/ then it came up with a index of directory, I opened the win 32 (my operating system). i am guessing i should download tremulous.exe because the other one comes up with a strange code, do i just replace the original tremulous.exe with the new 2mb one?
Yes, download tremulous.exe than drag it into your Tremulous folder, it should ask if you want to replace, hit yes and bingo!
Than open Tremulous and it should be all good.
You should probably rename the original first, just in case.
