Okay man, I understand. I'm trying to figure out what the problem is. Give me more than just two minutes.
edit: okay, Slim Trashman has the same tools as me installed and it won't work. I need to do some more research on this thing, which I can't do at the moment. I've removed the mod from the site, if anybody can continue to beta test it that would be great. Here's what I'm doing:
I use Windows XP SP3. I have Alice and Rick's XLive Wrapper installed (search our file archive or Google for links). I put guards.asi into the root GTA IV folder. The ASI log shows that it loads fine, as seen above, and it works perfectly in game. I will keep checking to see why I can run it but nobody else is able to.
