Hi,
We don't have an automatic update script but we are ready to help you to upgrade your demo version.
Please contact us via support form for instructions. It's Free!

If still don't want to contact us you can
1. Save your contacts into temporary file using "export" (optional if you want to keep your contacts)
2. Uninstal old version. Delete Old db.
3. Download & install the new version.
4. import contacts back from the temp file

Thanks.
