Is there any way to stop the pop up?

On another subject, is there anyone I can contact to get my MC 12 key working again? I've had some computer problems and some major upgrades and so have had to reinstall several times. I thought we had ten a year.??
There isn't a yearly "reset day" when all ten woud be resetted. Each restore comes back a year after it was used.
In the past JRiver has resetted the restores upon request. Probably they can help you.
In general, MC13 (or 14) is not a stupid upgrade. There are a lot of new or improved féatures. Check the link in my signature for the complete change logs. A newly purchased upgrade gives you a license that is valid for the recent MC13 builds and MC14 (actually, you'll get an MC14 license even if you start the purchase process using MC13).
