Entered the wrong License Code in for Ray Plugins

I have the free version of dolphin, and free versions of ray plugins (with ads). I went to Dolphin's admin page, then chose "Plugins" and tried registering all the Ray Plugins. I entered the wrong license code in for the "messenger", and now it says "enabled", but its the wrong code I put in, so how can I go back and put the correct code in now? The only options I see is to "enable" or "disable". I tried choosing "disable" and thought it might give me a chance to enter the license in again, but to no avail. Thanks
