Neither AVD nor application show up

Hi!

I already wrote a small application for android before and everything worked nice.
After a week, I came back to android, and AVD doesn't show up anymore.
I think it starts, because it says that it's running when I try to delete it, but it doesn't show up on the screen.
Also, when I try to run application, console doesn't show anything, and nothing happens basically.

I don't know what to do.
I recently upgraded my Ubuntu, I don't know if that might be connected.
But after I did that I redownloaded and reset everything up.

Any help is really appreciated!
Thank you!
