Ok, so you've got the beta (version 2.2.2) installed and running now?
Please select the "beta version" option today, then fire it up tomorrow sometime (I only check versions once per day).
When the GUI opens, it should prompt you to download the new beta (version 2.2.3).
Maybe I should be more aggressive on checking for new betas? Should I skip the "once per day" thing and check every time you open it? Opinions?
