Lost all preset ratings after installing Cubase Artist 7

Hello.

Until this afternoon I had a collection of VST plugins that I was trying with the trial of Cubase 6 Elements. Waiting for the bought copy of Cubase Artist 7, I spent some time evaluating hundreds of presents and giving ratings to them. After installing Cubase Artist 7 I deleted Cubase 6 Elements (trial) and all my ratings vanished.

While I also made a text document with the list of the top presets, I’m worried about having wasted time. In any case, before installing Cubase Artist 7 I did a complete backup of the disk (well, almost, but I think it should suffice: the Lion boot partition and my user folder), so I hope I’m able to restore the data. But need to know how to do that.

Thanks.

Is there anybody here?
