converting SX versions to CPR

So I read this post:
And I downloaded the Cubase SX2
However when I try to run SX2, it gives me an syncrosoft Licenser error:
I also saw that I needed to download a version of elicenser control, which I did.
Problem is when I tried to install the eLicenser, I get an error message saying can’t install because a newer version already exists!
So what next?, I would be greatful for any help, as I would love to open some of these old projects and re-work them a bit.
