I purchased wavepad 4.28 from this web site on 9/29/2010 and see there are updates above 4.28. After looking at the version updates i believe that there were newer versions available than 4.28 when i downloaded mine. Question is if i update my 4.28 version will i have to have to pay the upgrade price? Also when i purchased 4.28, i don't believe that the version was shown on the web site when i clicked on download or did i just not see what the current version was? I still do not see what the current version is on the home page.
