I attempted to upgrade from MC24 to MC25, and it isn't accepting my license for restoration. I downloaded it on Chrome after getting the email with the registration codes for MC17, MC21, and MC24 emailed to me. I used the code for MC24 to generate an email with the mjc file, and when attempting to restore, I am getting a message that the license file isn't valid for media center, with the option to purchase a new license. I went ahead and uninstalled MC24 at this point, and tried to restore MC25, and I got the same result. One complicating factor is that I still have a version of MC17 on the computer that I don't use, and I am not able to uninstall it (when I attempt to uninstall, I get a popup that the run dll initialization routine failed). This was all done in the appropriate windows license sections. Am I wrong in reading that the upgrade from MC24 to MC25 is supposed to be free?
