Deferred OS Update assistance

I received a message on my LG Revolution yesterday stating that an update had been downloaded, and I could install now (@ 71 minutes) or defer. I deferred the install 'til 11PM last night, since I needed to use the phone. As far as I can tell, the update did not take place automatically - I left the phone on, sitting on the charger. If I try to select Install Deferred SW, from the About Section in the phone, if fails with a message stating "" has failed, please try again. I'm trying to allow the upgrade from LG_VS910ZV7 to ZV8.  Is there a way to correct this, and actually get the update to take place?  Thanks!
