Nitro Productivity Suite - Purchased 5 months ago (Trial will end in 7 days ???)

[DLFS 0]

I purchased the product 5 months ago. I have the serial and license numbers from the date I purchased Nitro Productivity Suite app. 

For the last 7 days, when I open the app to use, I see "Trial Mode" and "7 days left to to Buy from official Nitro online store, to end this Trial."

If I already officially purchased this product 5 months ago, why I am receiving these alerts every time I open the app?

Hello @DLFS,

Thank you for reaching out to us through our Community Forums!

Did the affected machine installed a major Windows Update prior to this issue?

If yes, kindly note upon the upgrade of the operating system or installing a major Microsoft update, the Computer ID is changed, as it is comprised partially by the operating system. Once changed, this will no longer recognize the original installation causing the program to revert to trial mode.

To fix this issue, I just made an adjustment on your license, so you can now activate your copy of Nitro Pro by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate.

Thank you for choosing Nitro and I hope this helps!
