Thanks for the feedback on Buckit. You're correct - we have encountered a few issues over the last couple of weeks.
Ironically, the main reason for this is that there is so much active development happening on Buckit at the moment. The good news however is that our development team is working on Buckit literally full-time and (to date) all reported problems have been fixed including the issues that Matt and Gareth have reported.
We'd really recommend that you give Buckit another quick try. It is completely free for 2 months with no obligation so there's not really much to lose!
Something else worth mentioning is that to minimize any future issues cropping up when we update the site, we now have TWO sites :-
http://buckit.co.uk - the current 'stable' release
http://beta.buckit.co.uk - the latest release with new features
You can use either site to access your database securely. Obviously the "beta" one includes the latest updates, changes and improvements with the option of logging on to the "stable" site in the event of problems.
Hope this information is helpful!
