Can't livetrace or mirror paths


New Member
I seem to be unable to live trace for some reason, the option to do so on the top bar has dissapeared, and I cannot live trace an image though objects>live trace>tracing options. The tracing options also do not allow me to preview for the option is grayed out.

I also wish to have a different design mirrored when using the path tool so both side are symmetrical, could someone point me to a tutorial or explain how Im meant to do this.

I am using illustrator CS5, cheers!
