I am also trying to understand this. From what I can see, you have an active membership, and it's a while ago since you renewed it. It should be active everywhere for you.
That it's a while ago you renewed it is good, since it might take some time for the membership takes effect after paying for it, but usually it happens within some minutes.
Could you tell us more about what isn't working? The D/T Matrix tool itself is public for everyone who is logged in. But there are a few extra fitlers that aren't. For example the loop filter and the D/T type/size filter. Is it one of those that you can't find in the Add filter box?
