Hello, i can confirm that the license key is not a .csv file but a .xml file. To get the xml file you neet to go to the product management page, select get key and obtrain the xml key file. Try also to see under tools/license activation/activated licenses. Please let me know how can I help you further. Thanks Marco
Purchased upgrade. When I go to my Digital Locker, I see the purchase. When I tell it to Export, it exports a  small CSV file which is invalid for upgrade, seems like I should have gotten a zipped up xml file. Am I doing something wrong or did they not attach a valid license file? Thanks.
