I am unable to access my private messages

[End Unsure]

Hey guys, I've been a member here for about a week now and still can't access my private messages. It says:

You do not have permission to access this page. This could be because of one of the following reasons:

1. Your account has either been suspended or you have been banned from accessing this resource.
   
2. You do not have permission to access this page. Are you trying to access administrative pages or a resource that you shouldn't be? Check in the forum rules that you are allowed to perform this action.
   
3. Your account may still be awaiting activation or moderation. (Resend Activation Code)
   
4. You have accessed this page directly rather than using appropriate forms or link.
   

any ideas as to why?

Just to rule out the obvious, while it is that I had some trouble with it I am pretty sure I have activated my account, I mean I can post after all.
