My fix for error 126 seems to have been a bad setting in my config file. Since I couldn't find it, the fix for me was deleting everything, redownloading the svn trunk, and starting over. I believe it was the config since I saved a backup and ran it on the new svn only to have it crash again. When I tweaked the config given to me by the svn, it worked fine.
I'm just starting to use these scripts, can't really help you out with troubleshooting yours. I wonder if our config files are what's causing the error 126. Something in the code insisting on it being there and the tutorial
viewtopic.php?f=6&t=1464 that guides us to setup doesn't have it?
