Hey Swaggy,
If you get this, the error tonight was wrong signature file for a3_epoch_assets_2.pbo.
This tells me you are not using the latest Epoch mod, even if you have downloaded it, you do not have the newest one enabled.
I will reply the same info at epochmod.com/forums for ya.
Double check your files with ease.
Go into your
Arma3-@epoch-addons folder.
The signature files should have 0302 in them, not 0301 not 0252.
If they do have 0302 in them,
Load up Arma 3, goto configure, expansions and make sure 0.3.0.2 is enabled and the others are disabled.
