Efile error code 388

I am trying to efile a T2 and get this error. It means the return is prevented from efiling because the return period overlaps a previously filed return.  I called CRA Help and we verified the date and time stamp  are not in conflict.  CRA said to call the software provider.  I called and we installed the latest software updates.  The T2 return is receiving the same  efile error when  attempting to efile.  Is anyone else getting this error code?
