Computer crashed - re-downloaded EmClient - Act Key won’t work.  Help!

If youhave a free version, either contact info@emclient.com, or get a new key using a different email address, if you have one available.  If it is a Pro version, go to the license manager at https://licensemanager.emclient.com/ and deactivate your old computer, then your license will work (the license manager info should have been sent to you when you purchased the license),

Thank you so much!
