WLM won't recongize me

I just made a new account for WLM and it’s saying that my account doesn’t exist yet, and I was wondering why.
Is it because my account is new and it has to register to the system or is it something else?
Any help would nice.

It should be instant. However, if you have used a long password, you might consider resetting it to something 12 characters or less, as longer passwords can be a problem.
