TinyGPS problem running demo code

Hi,
I'm trying to run demo code for the GP-635T TinyGPS but I can't seem to get past :

Arduino: 1.5.4 (Windows 7), Board: "Arduino Uno"
sketch_jul07a:4: error: 'TinyGPS' does not name a type

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

Anybody knows what's going on here?
Thanks in advance!

Should there be libraries to install as it looks like there should be and they are not.

I'm trying to run demo code

How can you be running code that won't even compile?

Hence 'I'm trying'
Erik

For some reason, the compiler can't find the code for tinygps.

You may have put the library in the wrong place.

After you install the library code, you need to close and re-open the arduino IDE because it only looks for the library files when the IDE starts up.

It was indeed a library problem, thanks people, it seems fine now! Seems, as I don't get a fix inside, but I''l check it outside later today!
