uploading songs to soundclick?

Hi all, I’m using cubase 6 and Superior 2.0. Both 64-bit. I want to upload my demo’s to soundclick, or any other similar site I suppose. When I do I can only upload one track not the whole song. I’m not sure if I’m doing something wrong or what, my knowledge of this kind of activity is very limited. If someone could help me out it would be great. Thanks

Export audio mixdown

When I tell it to export it says “The export range is empty. Please set the left and right locators” What does that mean? What are the, and where do I find the left and right locators?

You really need to read the manual about exporting a mixdown.
Page 485 covers this. Rather than someone typing it in here just check it out.
The locators are covered on page 42.

Select a part that is the length of the song and hit p. Watch what happens in the time line.
