Warning unsupported type + DOF not selectable

Hello,

i have a question regarding the loads and supports in my part. I put all my loads on surfaces. My distributed force is supposed to go around the window in the path that i have partitioned while the pressure is placed all over the backside of my part. After placing the loads i clicked on "measure weight"  and "calculate" and the following message popped up.

Warnings:

Force 2 treated as pt load.

Pressure 2 ignored, unsupported type

Support 3 treated as pt support.

Support 4 treated as pt support.

Moreover the top support (shown in image) is supposed to have a DOF regarding the rotation around the x-axis. But it is not possible for me to select the rotational DOFs at all. 

All images below.

Thanks a lot for any tips on what I am doing wrong.

Kind regards, 

Dogan
