We have found an issue with our current build (3.18.0) and we are taking it offline while we investigate and correct the issue. It should be available once again next week. Stay tuned to this blog or Twitter for further details.
Thanks for your patience.
*Update: CDP 3.18.1 is now available for download. More details to come via email update next week, or get a jump on the 3.18.1 release with details from our wiki.
