ACW 3.6.2 Two questions

[tavish69]

Hi all. My first question is, can you have more than one mod installed? Ie...DME mod aswell as ACW?
My second question is, I had installed ACW it ran peachy. Then I wanted to go back to the standard Empire game through steam.
I changed the ACW mod to vanilla settings( I presume that is standard for Empire)
When I went to steam to boot Empire it said running then nothing happens?
So is it ACW or nothing?
Also before this I installed DME which ran great. then repeated the vanilla thing in the mod.
Standard Empire booted up fine in steam so I'm a little confused.
Any help appreciated.
ps... When I installed ACW it was a fresh install of Empire with warpath.
