I thought it might be a good time to repeat what the latest versions of Harvest are. Currently, the correct version is 1.14 or 1.16. The 1.16 version is only used on Steam, and fixes a couple of Steam-related issues. This version has the same features as the 1.14 version that everybody else is using. If you got the game from Reflexive, this version should already be 1.14, otherwise follow this link:
If you are a Steam user and want to migrate your non-Steam copy there, you can do so by activating the product on Steam with your Harvest license key. This option is only available if you bought the game here before March 2009.
