Last night I installed 11 Sep 2006 version and had nothing but errors, the same kind I've reading about (404s, query strings with many &), so I gave it one more chance using Chemo's Official v2.1d version and to my surprise everything is working perfectly now!!!!
Someone added the "additional_install_files.txt" that just messes things up! Funny, the 2.1d version is so easy to install yet someone added another version that is supposed to make the installation easier. Sheesh, it could hardly be any easier.
Don't waste your time with the other versions, always stick with Chemo's. I am a software developer and I contributed some contributions and I was amazed how easy and clean this installation was considering all that it does.!
Cheers to you Chemo, you definitely know your stuff!
