My license is not expired and EMclient close it

Hi,
My license is not expired and EMclient close it.
I’m trying to contact support and nobody answer to me.
Is this company(EMCLIENT) ok?
Any body can help me there?

I see you only have a version 9 license and you are trying to use it with version 10. That won’t work.

If you want to use version 10, you can purchase an upgrade to 10 here.

Or you can purchase a lifetime upgrade, so for all future versions here.

If you don’t want to purchase an upgrade, please follow the downgrade instructions here to go back to 9.
