I tried PRO and lost it in an update but I wouldn't buy it again the changes are not dramatic really not even noticable your not missing anything I won't waste another $24.00 plus it only last for 6 months of technical support/updates which I got mine in 6/2006 and never seen an update until now 9/2007 when I updated and lost my PRO becasue after six months you don't exist in there system anymore so you can keep what you have but if you update you start over more or less, hope that helps with your decision I got this info from other pwople on this site so other people agree
