If I don't capitalize them, the game doesn't recognize it (at least I think that was the problem...my typing accuracy isn't what I'd call top notch lol). I know TheChronicR is from a different country than I am, however I don't know which country. Do either of you two play on an English version of the game (perhaps that's the difference)?
When I was having my problem with it (before I found this forum), I asked about it on the official forum and that's what I was told to fix my issues.
