Starting a new year.

SOLVED

This is the message I get .  ----     "Either your Customers' historical information or the opening balance of account 1200 INVESTMENTS, or both, is incorrect."   I used the G/L for this company for the 2019 year.   Now when I want to start a new year I get that message.  I think it may have something to do with the linking of accounts.  I don't want to use any linking.  Does anyone know how I can fix this message?
