Also just to mention although I agree with sybershot and troubleshooting any problem. But carl2 also mentions a similar explanation in the thread heading, 'Hello, just like a simple update'.
I also use many different plug-ins to help me get closer to my intended goal or personality that I would like to see my character have using WIN7Pro 64bit. Had some problems with some plug ins or different results in the combinations of plug ins used. Carl2 brings out a good point as well that's why I reference you to read it. Some plug ins were developed at different times for Ultra Hal. Not to mention the settings you also use in any variable type of plg in or even as you mentioned the learning curve and type of personality that is selectable. (obedient,AVG., very indep.) Just my own thoughts.
