If your computer died, you're probably not going to have better luck with any other software, it's still going to die unless you solve that problem.
I don't see what "the user manual is crap" has to do with "getting support" which implies that you're going to talk to someone about your problem. "The user manual is crap" doesn't tell us what problem you're having or what information you were looking for that you apparently could not find.
The only video you need to watch is the 40 second configuration video, if you go watching lots of videos to figure out how to get started, you're probably going to confuse yourself with a lot of advanced information you may never need. There's a lot of guides linked from ISBoxer.com, including the Quick Start Guide: http://isboxer.com/index.php/compone...de-quick-start
... which should help you with whatever problem you had that "the quick setup didn't work", but I don't know what you're stuck on.
If you are accustomed to Keyclone, there's also a Guide to ISBoxer for Keyclone refugees: http://www.dual-boxing.com/showthread.php?t=30460
I wouldn't say it's a lot of trial and error at all. If you're spending more than a few minutes trial and erroring to get the basic setup from the Quick Setup Wizard working, you should ask for help.
