Broken Plug in – Indifferent Support

Since the upgrade of WordPress, this plugin has shown numerous different errors. Their support forum is full of reports of issues – anything from not working at all to navigation not working, but the responses from the developers are few and far between and there is no co-ordination of replies on their forum, yet they try to encourage customers to spend $75 on the pro version which I believe is having the same problems (but I don’t need or want all that extra stuff). I wonder who would spend that much on such a buggy product, and this is not the first time there have been problems with it.
Its a big shame as when the plugin did work properly it was just about the best events plugin available, but now its basically a waste of time.
