"Unable to locate the Serial Number" when activating

[amrice@comcast.net 0]

I am having the same problem.  I bought new computer and wanted to come up quickly with Nitro Pro by downloading a Trial copy, knowing I have allowance for 2 Active installs.  I cannot figure out how to convert the Trial version to my active license.  When I enter the license number from the old install, I get "Unable to locate the Serial Number".  Of course this is off hours and there is no human contact.  The Email form forces me back to the Active Screen where now I am in fricking loop.

Can anyone help me?

I am having the same issue.  About a week ago, I had to update my Windows 10 operating system.  At that time, I reverted to an earlier version of my computer bios entotal.  Since then, Nitro doesn't recognize nor will it accept the serial number to reactivate Nitro.  Nitro also indicates that my trial period has ended but will not accept the serial number.  I also verified the serial number through Cleverbridge and tried to reenter it to no success.  The only other bit of information I can provide is when I try to use Nitro,  I receive Error Code -7089.

I posted another service request to this site.  This is a very frustrating site.  How do I submit screenshots?  I sent link to document on Google Drive
