Hi there! I have attemped to install the demo on 3 different PCs and encountered the same error messages. On the first time running maxim after installation, I get an error message "license has expired" without me clicking any button. It just pops up after running maxim. The "signature" box already has a long signature while the other boxes are empty. After this, I will then copy my demo license email, and it is correctly entered into the maxim program. When I click "ok", I then get an error message "You cannot enter a second demo license." I have not used my demo license before today. Of the 3 PCs, 2 have never installed Maxim before. 1 already had maxim installed a few weeks earlier, but no license activated. I have tried reinstalling Maxim as well, but same series of errors will occur. Hope you can advise, thank you!
