I'm trying to register my purchased (boxed) upgrade to NX2 at www.niksoftware.com, and I'm finding that the product key won't be accepted at the site. It's a series of 5 digits in 5 groups on the CD box, but at the site it asks for 6 groups of digits as follows 5-4-4-4-4-4. That's enough space for all 25 digits, but I get a message saying: "Please check your information and fill out all required fields". And it highlights the last 4 fields as being incomplete or incorrect. Luckily the Product Key is accepted by the installation routine. I had the same issue with NX when I bought it, but registering Color Efex 3.0 (for Photoshop) worked fine. Any body know how to get around this? Thanks!
