2G Base Station - 4G Upgrade

I was sent the package to do the 4G upgrade. Since I have installed the new 4G piece, my base station is not connecting to my app. My app reports that 'There is a power outage' and then when I attempt to arm the alarm I receive a 'Base Station Busy' notification stating that Simplisafe is 'currently attempting to update settings from (your) Base Station".  Has anyone else had this same issue after installing the new 4G chip??
