Upgrde from FREE to PRO. Reinstall app?

Hi. I am seriously thinking of purchasing the Pro Licence since eMClient has proven a really reliable and user-friendly app.
If i Do, does it mean I have to reinstall the Pro version and reconfigure everything? Or is it just some activation licence i Enter and i just go on using the eMCleint?

thanks for your help,

All you do after purchasing the Pro License is change the activation key. Nothing to reinstall or configure. :wink:

Thank you very much. I thought so.

ps If i purchase no license, the free version remains functional as it stands now and with limited features, correct??

Yes, that is correct.
