EnergyPlus 8.9 added an annual reporting frequency (see here for the changelog), and it looks like that is tripping up the viewer. Do you have any outputs set to report at annual frequency? If so and you're running one year (or less), then change those to run period frequency. If you don't have any output variables with annual reporting frequency, you could try editing the ESO file to delete this line in the header:
6,1,Calendar Year of Simulation[] ! When Annual Report Variables Requested
If neither of those work, it may be that modifications in the code of the viewer are needed.
