Contact sales dept.. Due to a violation of our policy... Cant activate account

My trial period is over, so I’m trying to input my free licence number but it tells me to contact sales dept… Due to a violation of our policy…
Where do I find link to sales Dept…?

Look on the eM Client website for contact details.

It may be that you have more than two email accounts setup in eM Client. If that is the case keep just two and remove the rest, then try activate the license again.
