RichJa Posted January 25, 2018 Report Share Posted January 25, 2018 I recently downloaded the trial version of Nitro Pro 11, which worked fine. I decided to buy the software and the vendor link quoted a price for Nitro Pro 11, which I accepted and paid today. I was provided with a serial number, but when I attempt to use it to activate the trial version I receive an error message to the effect that the serial number is from a different version of Nitro Pro. On investigation, it appears that the download and serial number that I received are for Nitro Pro 10. Please help me to sort this out. Thank you.
