Empire log in problems?

im after trying to log into my empire account and got the following message:

"Sorry you either do not have an account with us or you entered invalid details. If you have an existing account with us, please use that."

there are then 2 options to either create a new account or to retry.

i used the same login details as i always do (username and password saved on login page).

ive emailed CS bout it so they should get back to me in bout 4 days....

anyone here experience the same?

and btw, i have ONE empire account.....
