Okay, so I recently installed Ubuntu 14.04 and from there upgraded to 14.10.
My installation is 64bit.

I have installed several other programs and all work fine. For some reason when I try to run Skype it doesn't open up, if I run it from the terminal nothing comes up. However, if I use sudo skype it does run and works just fine. I've tried deleting my /.Skype folder and that momentarily solved the problem until I restarted. 

Anyone know how to fix this?
Also when I start my terminal I get this before anything else comes on it:

S: Command not found.
