I used zd for a couple of years and eventually gave up on it because it was very slow to sync to gmail etc. If the current version of zd can deal with fairly large email account better than 2.0?

I still have zd 2.0 (10514) installed. Should I attempt to upgrade it or so should I remove it and all data files in order to test 7.1.4?

When checking for updates, zd 2.0 itself says there are none available, so maybe I have to start over?
