I need to use some classes belong to mx library, but when I try to import it Flash throws me an error that it can't find this library.
How can I import it to my project? I'm using Adobe Flash Professional CS5.

You may try downloading the Flex SDK, get mx.swc from Flex\frameworks\lib and add it to your library path (ActionScript Settings > Library Path) in Flash CS5.
