The version should be listed with the download link at the very least.
Old, Zombie has updated this to version 0.05 a year ago. Works for all three versions I assume since he doesn't specify which isn't like him if it was version specific.
I can't find this one so you'll have to point it out. Actually, don't bother.
I believe this is a vanilla only mod since most references for it are pre entrenchment.

The mod seems to work with the beta 2 verison (From back in 2008) So Vanilla sins second beta... Waaaaaaay out of date. Use the dev.exe instead of this.
So you're using mods that are incompatible with the version of the game you are running most likely since the most recent one you're listing here is a year old with it's most recent update.
What you need to do is know what version of Sins you are playing and look for mods that are for that version rather then guessing and crashing all of the time.
Where should you look? http://ricksgalaxy.homestead.com/links.html of course.
