Honeybee[+] Failed to load results from empty file - Annual simulation

I get the following error message when executing annual simulations with Honeybee[+]. The error message was produced while running a sample file. Am I missing something or is this an installation issue? I am able to run daylight factor simulations without any errors.

"Loading the results from result files.
Runtime error (Exception): Failed to load the results form an empty file: c:\ladybug\honeybee_005\gridbased_annual\result\sun…scene…default.ill
Double check inputs and outputs and make sure everything is run correctly.
