SDUTTON  Redstone Software has since reversed their upgrade policy and is offering a free upgrade to all users who have purchased Vine Viewer in the past 30 days (providing a refund for those who already paid for the 3.0 upgrade, which includes me). In light of their sincere apology emailed to current Vine users, I would like to retract my previous review and give them five stars.

SDUTTON  I just purchased version 2.2 a little over a week ago, and emailed their customer support about a free upgrade to version 3.0. They told me I had to pay the upgrade fee of $15 just like any previous owner. Eerrgh. It's not the $15 that grinds me . . . it's the blatant disregard for customer relations. Most companies have some small window, a month or so, for those who just purchased a product to receive the upgrade for free. It's a clear indication of how they really view their customers.
