Unity 5 - Problem?

Hello guys,

Ever since I uploaded to Unity 5 I have had a number of problems with Unity.

This one has me stumped however it’s probably something simple though. Anyway I have spent the last two days trying to find skyboxes other than the default, looking through all the packages trying to find them only to find they don’t exist,so, I downloaded a skybox pack and applied one of them to my scene and went to run it and this happened:


And I cannot figure out what happened to my scene! What have i done to make this happen and how can I rectify it.

If I disable then re-enable the FPS controller I get the game view appearing correctly - then when I run it, the same as above appears, then stays like that even after hitting the “Stop” button.

Thankyou and Regards,
CK.

Anyone have any ideas at all? Or should I just re-start the project again for the third time?
