RTC after power cycle

I am using the STM32L1C8 with either its LSI oscillator or an attached LSE (32.768 kHz).  Either way, when I load the code through Keil the RTC module updates properly but when I do a full power cycle the RTC module doesn't seem to update.  I don't get any interrupts and when I force a read the clock stays at the default time.  I read the date right after the time, but it doesn't seem to matter because it never gets to that point on its own because it never gets an interrupt.  Once again, it only works when I first flash the code through Keil, not after a power reset.  Dose anyone have an idea of what is going on?
