Plugin setting changed when moving project from C5 to C6.5

Hi, I having problem here that I create my project and mix it in Cubase 5 with some plugins, then I move the project to the studio which is Cubase 6.5 and having the same plugins, the project can be open, but some plugins that I apply to track was like become default setting, not the setting I set in cubase 5. Anybody face this problem before?

Best Regards
