utorrent 3.1.3

I don't have a good connection of wifi on my laptop so I go to the cafe and rent a computer to download torrent into my portable HDD using utorrent portable. All is well until the update for 3.1.3 arrives. It doesn't seem to retain any data of the previous session and always ask me to install. When I return to the shop I see the utorrent empty of loaded torrents I was seeding last time which is frustrating since I need to reload it again and some files are too large it takes time.

The cafe has a deepfreeze so data from the last user before shutdown isn't retain.

How do I cure this?

Can I just use the older version?
