Extracting patches or using old TI Backups

[spiral]

I previously owned a TI Polar and Snow, and now i have a TI Desktop. I only used them as hardware synths.

I have a backup of my Polar memory from last year and tried to update the TI Desktop with it so i could grab all my Polar patches but i get an error that says it is from an older Virus Control version and won't work. My questions:

1. How can i recover all my patches from the TI Polar backup file (.vtibackup), either through extracting the patches or getting them on to a Virus so i can pull them off again?
2. If the backup isn't used for storing patches, what is the purpose of it?
