Do you have your graphic card drivers update?
For running in console mode you have to go in:
Programs->planeshift crystal blue
Right click on Planeshift - Tech Demo, then click properties.
Then, at the end of Target field add -console so it looks similar to this:
"C:\Programmi\PlaneShift Crystal Blue\psclient.exe" -console
Start up your client (maybe not in fullscreen mode...), you will get another window, a console window, now, running in parallel with your client.
Some text will be displayed there. Do a nice copy and paste everything especially the last things, in here.
