Metasequoia modeler tutorials and Keynote translated plugins

[Creatura]

I have reinstalled Windows 7 and I had to start Meta as a first time start-up.

I copied all of the plug-ins in corresponding directories but they act as if they don't exist at all.

Can anyone tell me what to do?

I'm running Meta 2.4.13. maybe it's incompatible?

[Edit]

I think I found the solution.
I am using an unregistered version.

[Another edit]

I registered and it works now like a charm :)
