There seems to be an issue with their server, I ran into the same problem. But they promised a quick fix for this on twitter IIRC.
Otherwise, the software is getting better and better. The new reports in the 7.2. version are great, the new familysearch overview is more of a gimmick than a real feature. Nonetheless, it is great that these huge updates are free of charge, never saw any company updating their software this frequent with new features.
