Hello Rian, and welcome to the forums
Plus has nothing to do with adding new custom emoticons, that's up to messenger. I'd suggest you to reinstall messenger (the version you have or the last update: 6.2.0137). Btw, when you try to add new emoticons, does messenger display any message saying why you can't add them?
