Can't Read all in Popup Window

For the last month or so every time I start eM Client I get a popup window (see attached) saying something about my pro license expiring. However I cannot read the whole message as it doesn’t fit in the window and the window cannot be enlarged or scrolled in.

How can I read the whole message? I assume that below what I can read there is a box that I can click that says “I don’t have pro license”, which I don’t. Is eM Client unaware, after a month, that they are sending out messages that no one can read or respond to? Do they monitor this forum?

Thanks.

Presumably you installed eMC under the “30-day trial” offer?
If so, I suspect your licence will revert to a Free one when the 30-day period is over and you won’t have to do anything.
