Payroll Formula Not Valid

SUGGESTED

Hello,

I purchased the payroll module last week and every time I try to process a paycheque, I receive the error message "The payroll formulas being used are valid only for session dates 2013-01-01 to 2013-12-31."  I have tried to update my version of Sage 50 Pro and I have the most up-to-date version as well.
Thanks for any help.
