We are sorry to announce that the December Software release has been taken down and the previous software reinstated.
This was due to an unforeseen incompatability with some historical data. We are looking into a resolution to the problem and will re-apply the release as soon as we are sure it resolves the issue.
The release in all other aspects performed admirably, however in order to ensure that all of our customers could operate effectively, we have undone the release until such a time where the incompatability can be handled gracefully.
Thank you for your patience and thanks to those who notified us of the problem so quickly.
