Can't get any class teleports (Astral Recall, monk tele etc) to show up in addon.

I've tried multiple characters but the spells show up on all of them. Try this:
Open interface options.
Go to the addons tab.
Press the + next to Tome of Teleportation and select Customize Teleporters.
Press View Spell List.
Change the spell to Always Show.

If that doesn't work, delete the file [Install folder]_retail_\WTF\Account\youraccountname\SavedVariables\TomeOfTeleportation.lua.

Deleting the file worked, thank you.

The next version will have a button to reset all settings to fix issues like this.
