Welcome to the forum.
There have been several SmartSound threads recently. See:
While there are others, they go back to before PrE included SmartSound Sonicfire Pro, as the client. With Sonicfire Pro, some things changed a bit, but I think that the first thread will be helpful. Be sure to see Steve Grisetti's Replies.
Hi Bill, I installed the software and it workd, I hope it lasts. Thanks for the help!
Great news! Thanks for posting of your success.
While on the topic of Sonicfire Pro, if you use SmartSound a lot, you might want to explore their Sonicfire Pro Scoring Edition. It is not free, but offers enough additional power, when using the Multi-track SmartSound files, that I feel it's worth the $.
Also, see this SmartSound article (note: with the addition of Sonicfire Pro (QuickTracks Edition), some things have changed a bit): http://forums.adobe.com/message/4912568#4912568
I have been a very big fan of SmartSound, since I first discovered it, with about Pinnacle Studio 5, many years ago, and now own about 75% of their entire library.
Good luck, and happy editing,
