Hello Scooterboy, and welcome to Seven Forums.
I think you may have linked the wrong item. That one does not seem to be related to your issue. If you could post back with the link of the instructions you used, we may be able to help reverse it.
However, you may be able to do a
system restore at boot using a restore point dated before you did this to undo it as well.
Hope this helps,
Shawn
