Yes this problem has just been reported : this is a circular dependency of challenges (see here). If you want to unlock the features, just edit the challenges.xml file, and change the achieve tag value from "false" to "true".
We have just uploaded new binaries, version 0.7.1b. My understanding is that the Mac OS binary is still broken and needs to be fixed by Auria tomorrow. But Windows, static linux packags, and src version are up-to-date.
