Nitro 10 is not responding property. Are there discounted prices to upgrade to Pro?

[pgreco]

I have been using nitro 10 but lately it is shutting down on me when I try to open or insert files.  I'm going to upgrade to pro, as I love the product, but my serial number is not recognized for discount....even though the site says that Nitro 12 or older should cost $110 for upgrade, rather than the $220 price

Hello @pgreco,

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

To further assist you, I just made an adjustment on your license so please try upgrading it again to Nitro Pro 13 with a discounted rate.

Thank you for choosing Nitro and I hope this helps!
