I did a stupid things and deleted the three modules (cblogin, moderator and online) from the module list INSTEAD of uninstalling them.

Now it will not let me reinstall these - I get the failure message saying I am trying to install something that is already installed.

If they are installed, how can I get them back on the modules list or ????

I managed to figure out that I can fix this by going into the server files and deleting these mod files. I was able to reinstall after I did this.
Just FYI.
