I installed the discussion forums, but made a few adjustments, wasn't my finest work.

So I uninstalled, and tried reinstalling and got a DB error message which I didn't look at too closely.

I just went and deleted the whole package from my server, reinstalled and got:

mysql error: [1062: Duplicate entry 'discussion' for key 'ctHandle'] in EXECUTE("insert into PageTypes (ctHandle, ctName, ctIcon, pkgID) values ('discussion', 'Discussion', 'main.png', '35')")

What do I need to do to have a clean install of an add-on?

And that leads me to another question: what do I need to do to make a completely clean Concrete5 core install, but still keep all my add-ons?

Thanks,
Dan
