Unable to save drawings

[ekea...@gmail.com]

Have been struggling with SU off and on for a while now. Just discovered SU for Woodworkers and it's beginning to come together for me finally. The only problem is that when I try to save my drawings, a window pops up saying I can't save, that I don't have permission. I am able to print them, however. Anybody have any idea what I'm doing wrong?

Thanks, Erik E.
