Rather than getting guesses here call Lionel and explain what you have like Rick and Vernon suggested.  If it's a simple firmware change you maybe in luck.  If it's hardware then all bets are off.  Either way the first call is to Lionel.  If I remember correctly the ones that were corrected from the factory had a silver dot inside the battery compartment.

When I tried out the 990 system, mine shipped with either 1.1 or 1.2. The Base Utility was unable to write and upgrade module for the CAB2 remote and I don't think I was able to upgrade the Base directly either. I contacted Lionel and they sent me modules for the Base and CAB2 to upgrade them to 1.3. From there I was able to upgrade to 1.52 and create a 1.52 upgrade module for the CAB2. Shortly after that, I donated the 990 set to a club in need and carried on with my original TMCC setup.
