titanium backup help

[jon-e-o]

I just flashed CM10 ROM on my GNex after doing a clean wipe. I have Titanium Backup and the latest backup was stored on my computer. I deleted the TB folder from my SD card and replaced it with the backup TB folder. But when I go into TB on my phone, there is nothing under "restore". I tried pressing restore all apps and data, but nothing happens. I have not done a wipe before ( and may never again). I thought TB was supposed to restore my device with all my apps and data. Any help would be appreciated!
