I have had media center since version 8. my laptop recently needed to be reformatted, and I lost my version of media center 11 ..I downloaded version 17...today I purchased it for $44.98....version 16 was loaded into my comp....when I requested update codes from j.river, they sent me valid registration codes for versions 8 11 and 17. I think I should be refunded my money for version 17, and if I do need to purchase 17 and can't be refunded my money, then I should have version 17 not 16.
