AfterWorld Survival Forum

Survival won't launch, it keeps saying "Error" With a bunch of symbols after it, and they it says, "Click OK to terminate program" I downloaded it straight from the website, the lite version, am I suppose to download the full version? This has happened 2 months ago and I gave up on it, so I decided to log into AfterWorld: Alpha to see how everyone is doing, and now I see Survival is up and running. I really want to play, please reply in steps how to make it work. I'm running this on a 2001 computer, if my computer is too old to run this, let me know.
