Please try this to get your avi loaded 1st.
Bring up advanced menu with CTRL +ALT +D.
Advanced ->Character -> Character tests -> Test female or male
If this doesnt work, then make up a folder containing a skin, a shape, a bald hairbase & some eyes (non Prim) & right click this folder & REPLACE outfit. That should then go on & allow your avi to rez. If you have trouble doing this, please contact the Phoenix Support Group inworld & they will pass you an avatar folder to fix you.
Hope this helps
