If you use the built-in SQL Access function Now(), you do not need to put hash marks ( #) in it. (They should only limit the date literal, not the date function.) Try
... SET PAYMENT_CC_DATE_PROCESSED=Now() ...
, ,
... SET PAYMENT_CC_DATE_PROCESSED=Date() ...
, ,
... SET Field1=value1, Field2=value2 ...
not
... SET Field1=value1 AND Field2=value2 ...
