The one avalible for download is the 12.8meg file [old 2.2 version]
Just had a play and lucked onto the link to download the new version.
looks like you should un-install your previous version before installing this.
also there are links on this forum as to what registry key to backup to save your settings before un-installing.
No doubt the correct version will be avalible for download in the next 24 hrs.
