PayRunDate Error

Solved - Thanks - I am trying to process a pay run this morning, however, this error keeps coming up. 

I have checked my clock settings etc. & even cleared the cache but it still keeps coming up. 

Any advice?? is it a known error?

PayRunDate Error: The date entered for Pay/Update Date must be no later than today's date (ATO error code: CMN.ATO.PAYEVNT.000199)
