Marketpress is not working correctly?

I am asking a question about one of my websites Even though the support is enabled on the dashboard, it will not allow me access in to ask questions there.

My first question is: I have done everything according to the instructions given. However, the product category is not connecting to the store. So it not showing a shopping cart and not allowing purchases of the music to be made. Can you please help me with this issue?

Second request: On the Classical Music page, the words Product Category: Classical Music...I would like to change that to just Classical Music and change the font color to white. Again, I do not know how to change this.
Any help you my give, would be most appreciated.
Thank you,
