PDMWorks and toolbox

Hello SolidWorks user,

I am using SolidWorks 2010, and PDMWorks. Then I have an Assembly in which to use the toolbox, then I save. then I opened the same Assembly, but on the other computer. But part of the toolbox can not open / check out so when I go to the Assembly, the auto parts toolbox is missing. Before the Assembly was open I've enabled Toolbox. There are several questions in this case:

1. How do I solve this problem, for part toolbox to appear.
2. How can the toolbox is not to be read only?

Previously, I thank you.
