New installation, completed successfully. Upon required reboot and starting the application, it tells me that the Trial is expired.
I figured this maybe was intentional and that I needed to do the extend trial the first time to get it running, so I extend trial, enter the new key, and it says my 40 day trial has expired.
I think possibly the keys have changed from MC17 to MC18, and MC18 is not generating proper keys yet. I would love to test out the product, but this isn't a great start.
