Download Impulse, register your game, and hit update.

in the game menu itself its the button that says "download updates", i think you can also update by right-clicking the title in impluse

current version is 1.011

the latest version is 1.011? becaues iv seen posts about stuff like .50 and .51, could those be for stuff that isnt trinity like entrenchment? you see im trying to get a mod working for sins and this person posted that  the latest version was 1.051 so im just curious also i still cant update, i hit the download update button and it takes me to impulse and theres nothing about updates their, i see no update tab

alright it appears i have yet another problem, for some reason i have 2 mods files one with the two folders that are mods i downloaded (these i recognize) the others are a bunch of weird things like Mesh and Game Info, the other file which has the exact same name does not have the two mods files i downloaded, but still has the the weird files like mesh and game info. This is a problem because its interfering with downloaded newer and funner mods, what should i do? just delete the one without the thwo mod files i recognize?
