I had Parallels 8 Enterprise, but am no longer part of the Enterprise, so i bought an upgrade to 10 on March 11 this year. Now it says my license will expire on August 26 and when I click "check license" it says it can't be renewed. When I click "about parallels desktop" it says I have the Business edition. I thought the upgrade I bought would have changed this to a standard edition. What can I do?
