This is only helpful if you're doing it the 1st time around.  I purged my trial version and reimported when I purchased the product, and I no longer have access to the section where you can modify your payroll setup figures.  This makes payroll useless to me for the rest of this calendar year as I cannot modify CPP and EI values to actual for appropriate pay periods between try #1 and current to bring things up to date.  Any suggestions?
