Free Matrikon S7 OPC Server?

Downloaded from the matrikon portal. I wonder, is it a trial or what?
Currently im not having access to my plcs so unable to try it...

I was under the impression from a Matrikon sales pitch that the downloads are full performance packages. There's a 30 day run time trial during which the package can be configured and run as normal. When the 30 days expires, the package will run for 2 hours but require shutting down and a reset to re-enable it. To get full time operation after the 30 day trial expiration, a license needs to be purchased.

You can probably find licensing info on your installation in the help file or in a document like this one, although I'm not sure how old it is, since it refers to hardware dongles and parallel ports.
