0.1.3.1 is not on CKAN - it only installs 0.1.3
Also, there are errors thrown in KSP.log by the following config errors in CONFIG_OPR_OMSEngine.cfg and CONFIG_OPR_OMSEngineTwo.cfg. There are lines which refer to NewModel but use the folder 'Part' instead of 'Parts', i.e. in both files, and should not reference Mk-X/GameData/:
model = Mk-X/GameData/Benjee10_X-37B/Part/NewModel
should be
model = Benjee10_X-37B/Parts/NewModel
