Some help please.

Hey guys i have a couple of questions?
First of all I have Ion Discovery DJ with mixVibes that cam with it.
1. How do you delete you collections in MixVibes?
2. How come some songs I use are already cued...I can't play them from the begining?
3. I have the version that came with the Discovery DJ..any updates for my version...having a hard time figuring it out.
4.Any instructions on the MixVibes program that I have for button functions.
5. How do you do away with an loop once you starting looping?
