I am running a trial version of Mathematica 10 on Mac OS X 10.9.4. Both ThermodynamicData and MineralData generally return errors like this:
Both examples are from the help documents when re-executing them. The same happens when executing similar commands in a notebook.
Is anyone experiencing the same problem? How can I resolve it or is this a bug?
Are you using a trial version or Student version?
See this thread
Trial. Thanks, that obviously explains it.
