Graphic bug on Water (Basic) and Skybox

Hi

I use the standard Water (Basic) and the (only?) skybox that is available via "import package". I put the skybox material under Render settings but my sky is all black.

#2: When I zoom in onto the water, the are no waves, just a flat surface with a little bit of reflection. It looks like scaled way too big but I tried all scales from standard to -10 to +10 on each field, no change at all. When I play around with the shader, I can at least see the texture but nothing will move.

I have Windows 7 and an NVidia GTX 570M. Didn't change any fancy settings in Unity afair. My driver is 2 years old but I hope I don't have to update it since I made bad experiences last time, so I want to use that only as a very last resort.

Anyone knows what could be wrong? Everything on DX is activated (as described in the sticky), I dont notice any other graphic bugs in Unity.

 

Please? I have the same problem with every skybox. Am I using the wrong shader or sth?
