Violation of Licence Policy

So I just got the following message “cannot reactivate due to a violation of license policy” on my free version of eM Client. The question I have is, how do you know what email accounts I am using with eM Client? I am actually using a personal email account and I thought eM Client was stand alone, so how do you determine if it is a violation without reading my settings or email?

Oh and a public answer would be good rather than the standard response you have posted on similar posts. Thanks

Hello Richard,
I cannot share with you how we determine business use. I was not able to check your situation on our licensing server as I found no license under your name.
If you believe this was a mistake or you’d like to purchase a license and be unblocked contact our Sales department: sales@emclient.com

Regards,
Olivia
