Problem with SoftwareSerial.h

Hallo,

Im trying to run a sketch that includes the SoftwareSerial library. Im in a Arduino 1.0.4 IDE and with an Arduino UNO hardware. I include the library as I learned:
#include <SoftwareSerial.h>

but looks if its not recognized, no highlighted text. When I run the sketch, doesnt verify neither what I thought is evident…

I checked if it was installed, and yes it is. Doing research I discovered the NewSoftSerial, which in the website advice theres no necessary to download on Arduino IDE versions higher than 1.0 because its already included as SoftwareSerial. The interesting thing here is that by typing NewSoftSerial, it gets highlighted. But doesnt help neither when the sketch is running…

Does someone has the same problem as me? Which is the explanation to it…

Would really apreciate some clarifying.

Thanks a lot,

When I run the sketch, doesnt verify neither what I thought is evident...

How can you run a sketch that doesn't compile?

But doesnt help neither when the sketch is running...

You ignored the advice not to use NewSoftSerial with 1.0+?

Does someone has the same problem as me?

No. If I have a code problem, I post the code that causes the problem AND I describe what the problem is - what the code does, what I expect, how those differ - AND I describe the hardware setup I'm using.

I can see that you included all but 3 of those 3 things.
