How do you know that the error wasn’t yours? Why didn’t you try to contact the plugin’s author about this by posting a topic in the plugin’s dedicated sub-forum?

If you are running 3rd party themes and plugins check for updates or report issues to the authors; they may need to add compatibility. FYI 2.1 was in beta for 3 months to allow them to do this.
If you are running WooThemes extensions, updates will be available as all code has been 2.1 checked.
@mikejolley,
While you’re absolutely right that in the “best of all possible worlds” the 3rd party theme folks should have been paying attention to woo’s beta process, I feel that there’s a customer disconnect. Some thoughts on that: http://wordpress.org/support/topic/a-suggestion-for-future-big-releases
I have the same problem and deinstalled woo commerce (I just started) and installed it again, a blue host chat indicated I should update regular, so it is my fault. Still I have the same problem and deactivated it for now.
Did you ever solve your issue? Would be great if you could update your review if you solved it!
For future updates, doing this is a great idea: http://docs.woothemes.com/document/testing-updates-using-a-staging-environment/
