The issue might be because of different versions. Please check the version of IDF file exported by DesignBuilder. If you are running the exported IDF with EPLaunch then make sure that version listed in your file matches with your standalone EnergyPlus installation.
You can open you exported IDF file in Notepad and check the object "Version" and then check the version of E+ installed. If the versions are different then you could try using IDFVersionUpdater located in EnergyPlusV8-6-0\PreProcess\IDFVersionUpdater.
