Once you complete the prologue and tutorial, you will be in the main menu selecting a campaign. Go back to the play game menu and select DOG TAGS. Select the title option and choose "curious fan". It should be available from the start. If you do not have this title then play any campaign's first chapter and you will have a template and emblem that will work.
In the 360 version it appeared that "curious fan" was acquired if you played and or completed RE5, it does not seem to be the case here. It is now saying a default title. If anyone can confirm or deny this let me know so I can update.
It seems that this achievement is glitched for some people wit the "unlocking ". I do not know what causes the glitch or how to solve it at the moment. I personally had no problems unlocking it myself. I will update as soon as I hear more info.
Looks like previous update has been resolved.
