Dear all, I used NP-Designer ver 1.00, when i save my project twice and then i close it. And i'd like to open it again, it cannot be open! There is a message "Incorrect Data Format (Please Update NP-Designer)". Is anyone ever facing this problem like i do? My friend also facing the same problem in his PC but there is no solution for that problem. I also already uninstalled and installed again that NP designer but not solving the problem. As note, my operating system is windows XP, and for more information i attach my saved file that i cannot open in my PC. Thanks to all. TesNP.zip
