Does your IDF have any autosized equipment/fields? If so, you need to run sizing calculations before running an annual simulation. If all of your equipment is hardsized, you can run only the annual simulation.
The empty .err file indicates a crash, rather than just a failed simulation. Try running the IDF with EP-Launch and enable View/Options/Command Window and check Pause During Simulation, this might give you a hint into what's causing the crash.
