terminate called after throwing an instance of 'std::out_of_range'

[ghost]

I am running your example. But after reading 93 line in main.cpp, it terminated.
the error is terminate called after throwing an instance of 'std::out_of_range'

This was found to be a result of not using the correct download commands with the large tutorial files. Though a more useful error message would also be helpful.
