hehe, if you are a new user I think you just ran into an implementation mistake of Kaldran, showing you a message that is only meant for existing users.
If you are an existing user check the changelogs shown in the updater, they always tell you if you need to remove something.
Was this a clean install or did you "update" an old ProfitUI install. Did you change anything or is this a pure ProfitUI install? Also if you get to character select, is it the one with a huge "ProfitUI enabled" text?
