lrosow 0 Report post Posted November 10, 2019 I am a long-time Nitro customer. Just loaded the latest trial version to a new computer. Attempted to enter my previous Nitro 12 activation code, but the system says it isn't valid -- perhaps I have to start from scratch with a new purchase? But beyond that, I attempted to open a new trial cloud account, and despite several tries, I haven't successfully received an authentication email. Nitro had no trouble sending me a "welcome" email, so why not authentication? Please help! Share this post Link to post Share on other sites
Leslie V. 0 Report post Posted November 11, 2019 Hello @lrosow, You have a Nitro Pro 12 serial number, please make sure you have the correct version installed. You can get the correct version 12 installer from this page: https://www.gonitro.com/nps/product-details/downloads I sent you a Nitro cloud email. Please check that and let me know how that goes. Cheers! Share this post Link to post Share on other sites
lrosow 0 Report post Posted November 11, 2019 Thank you, Leslie. I unstalled and reinstalled using the link you sent. But when I try to enter my serial number (found on the "About Nitro..." tab on my old computer), I get the same message: "The serial number does not exist." I have double-checked it for accuracy. It dates from last March, and Nitro 12 was certainly active on the old computer. I see the cloud email -- haven't responded yet. Thanks. Share this post Link to post Share on other sites
lrosow 0 Report post Posted November 11, 2019 Oops! Cancel that! I see what I did now -- downloaded the link to Nitro 13 instead of Nitro 12. So I suppose what I need to do (since it makes sense to upgrade) is pay for the new version (full price?). Thanks for your help. Share this post Link to post Share on other sites
