I was running through the installation and somewhere along the line I got stuck. It was giving me errors about mysql, but everything matched the requirements needed to run the roster. Then I went back to finish the install and it said roster was installed and i should remove the install.php and install/ folder. then I went back to the roster page and it says the following error

Cannot get roster configuration from database
MySQL Said: 1146: Table 'roster.roster_config' doesn't exist

You might not have roster installed
INSTALL

thanks for any help given

Actually I came across this post and this is a lot easier for anyone using dragonfly
