Your serial number "over-flowed" - as in the number is too large.  The
serial number computations are performed using 32 bit arithmetic. 

Your serial has 11 digits.  I would limit the serial to YYYYMMDDXX (10
digits).  This gives you up to 100 updates per day (00-99).

There are multiple discussions in the list archives on how to recover
from this.  (In other words, I don't know how to do so right off the
top of my head.)
