If, and that's a really "big" word, you just go to your "WoW\Interface\AddOns" folder and delete just about
ANY addon (not JUST Carbonite), you really aren't "uninstalling" it. You also have to delete all of the addons "SavedVariables" files to completely uninstall it.
Now, in Carbonites case (as with most other addons), you would go to your "
Path to your WoW folder\WTF\Account\ACCOUNT NAME\SavedVariables\" and delete any Carbonite files you find there. Carbonite
ALSO puts a "SavedVariables" file
IN EVERY ONE OF YOUR CHARACTERS THAT YOU USED IT ON "SavedVariables" FOLDER. Those particular files you can leave behind, though, since they only contain that characters known flight points (Flight Masters). If you really want to be thorough about it, in Carbonites case anyway, you would have to go to your "
Path to your WoW folder\WTF\Account\ACCOUNT NAME\ServerName\CharacterName\SavedVariables\" folder
FOR EVERY CHARACTER THAT USED CARBONITE and delete the Carbonite files there also.
I've seen posts on a couple of WoW forums about people having problems with WoW doing odd things after an addon has been "uninstalled" (or deleted, really) that their game didn't do until they used the addon they just "uninstalled". Typically, it's either things not showing up from the default UI, or they show up but at an odd spot. The fix for that was usually deleting the removed addons "SavedVariables", so that no trace of it remained. If that didn't work, the recommended repair was to back up your "WTF" and "Interface" folders and reset the default UI, then add your addons and saved variables back in later. Reinstalling World of Warcraft is usually only recommended in extreme cases where absolutely nothing else worked. You might not have known about that, though, so you did the only thing you could think of that would definitely fix the problem. A less intense solution, but possibly more lengthy, time wise. IE: It might take more time to reinstall WoW then to go through the other steps.
The solution for the dungeon "eye", and several other fixes, is also in the first post of
This Thread. If you don't feel like going through the code to repair it (or don't know how), you can also find it already done for you
Here.
Of course, with MoP going live at midnight, this just might all be moot. We all know that Blizzard doesn't always keep things the way they are in the Beta tests when they go live, so I'm waiting to see how bad things are. I intend to be playing WoW when MoP goes live, so if WoW addons break and you hear a giant scream from the northeastern US, it's just me.
However, the way you fixed it worked and you're back playing WoW, albeit (the way it sounds) without Carbonite.
