Certification what does it mean?

So in 2007 I took a Router OS Training course. It now says that I am expired. Did I loose my credentials as a Mikrotik ROS certified individual? Or does it just mean that there is a new system for the ROS training courses. I do not know if my course was equal to the MTCNA. Any ways this is what it says when I review my last cert.

Certificate is expired!
Expired on 2010-01-31

My question is… Do I need to take the MTCNA or can I take the MTCWE? I really want to take the next level of the Router OS training I just need to know what I can take. I feel that I am pretty versed but I want the proper certs. Please any of the trainers chime in on this topic. Thanks.

Sincerely,
