Yea Celtic, i've heard it many times. Ratings and licenses are not the same.
Also i found out what you have to do for your Multi Engine rating.
From Lasors .

Section F3.3
>>>
"Revalidation of Multi-Engine Piston (Land) class ratings
requires a proficiency check with a JAR Authorised
Examiner within the 3 months preceding the expiry date
of the rating*. In addition to this, there is also a minimum
flying experience requirement of at least 10 route
sectors within the validity of the rating. The experience
requirement may be substituted by 1 route sector flown
with an authorised examiner that may be undertaken as
part of the proficiency check. A route sector is defined
as a flight comprising take-off, cruise of not less than 15
minutes, arrival, approach and landing."
* Provided this check is flown within the 3 month period,
the new rating 12 month validity period will run from the
date the old one was due to expire. For revalidation of
instrument rating if held, please refer to Section E1.5.
