The 2.3 service pack is out, which involves a new download of the entire package, uninstalling v2.2 and installing the new one. Quite a few fixes in it, from what I can see. Not sure whether the recent sale carried v2.3 but its easy enough to check what you've got.
The main reason for this heads up is that the extended download period ( which is provided free for this purpose ) is time-limited, so I should pop over there smartish and grab it if you need to.
However, having noted the amount of problems that have arisen after people have updated to 2.3, with a lot of them returning to 2.2, I have decided to stick with what I've got.
CS have addressed some of the issues in their 'knowledge base' with workarounds, but that's not what I consider acceptable for payware - even at sale price.
