I'm not doing this to advertise my gaming community, but to provide a full guide to this very same problem. I do not have anything to do with the SourceBans team nor an author of Sourcebans.
I just want to help people in a similar position.

I will allow Alliedmods.net SourceBans team to use this if they like for a possible troubleshooting and or FAQ guide in the future if they so wish to, if so please keep it copyrighted by us..
