That will be prefect!! Hope you can finish it ASAP.

I have did some testing on your site last night and I found some problems:

1. The shoping cart does not update automaticly.
      As a guest, I add an item in my shoping cart and later I when I add another one, the cart just shows the orgianal one.
      As a regietered buyer, no problem to adding two items, but when I try to pay for them, I can only pay for one item.

Therefore, buyers can only purchase one item at a time.

Furthermore, the items in the shopping cart can not be changed, they can only be empty.

These will cause a lot of problems for the buyers and not good for the sellers neither.

2. After purchase, some times the download button is not working. I have try to pay the item as a guest buyer but the site did not ask me to fill in my email address. When I finish the purchase and the download page shows up, I have try to click the download button for many times and it did not works. So I refresh the page but it goes back to the home page and I can not go back to the page with the download button anymore.

My suggestion is forceing the guest buyer to enter their email address before they pay and sent the download link to that email address after they pay. Or even better is to force they to regeister before they buy anything.

3. As a seller, I can not edit my listed item. Everytime when I click edit on the items, the site shows ' there is something wrong'.

4. The upload speed is slow. Maybe a 'Remote Upload' funtion will solve the problem.

5. I suggest you add 'perfect money' in your payment methods. Also you can sell perfect money vouchers for the buyers who do not have perfect money.
