Advancing to a new calendar year

We run Sage 50 Canadian.  On advancing to Jan. 1st, I got and error message that "An error occurred while moving employees' year-to-date payroll information to last year.  As a result, the new calendar year could not start."  I tried the Advanced Data Check, but it found an error it was unable to fix.

How can I fix this.  I found an article recommending that I delete historical data, and I did this year by year following their instructions.  However, the problem persists.

Can anyone help??

Thank you.
