Forum:Willowtree Help?

I started using Willowtree to mod weapons and here are the problems i have:

1. Character wont go above 50, i choose 70, and 61, but he stays at 50.

2. Some weapons i make are showing up, but not all, even if they are 'legit' according to http://blmodding.wikidot.com/gear-calculator

3. My shields and class mods wont show up

Does anyone have a site, or guide, that can help me solve these problems ?.?
