You may have mistaken the payment options.
When you attempt to purchase an item you are given two choices:
1) Buy with prepaid credit (PayPal or Moneybookers)
2) Buy instantly with PayPal only ($2 surcharge)
You can deposit money into your prepaid credit account here with PayPal or Moneybookers – a lot of people do this to make multiple purchases in the future easier (and cheaper). You can also earn money into your account here by referring customers or selling items on the marketplace. This is prepaid credit and is displayed at the top next to your name.
If you don’t want to deposit money into your prepaid envato account here that is totally fine – you can purchase the item directly with PayPal – this involves a $2 surcharge – people tend to choose this option if they do not plan on purchasing any items from any envato marketplaces in the future.

Wack any bug reports over in that thread
I’m sure with such a complicated system a few minor hiccups will occur. They’ll be sorted soon
Most should allow sockets. Any linux host should support local sockets, ipv4 sockets might get a little tricky and you’ll just have to try to see what firewall lovelies are in place.
Hosts like godaddy may block certain outbound ports your script tries to hit, or connections back onto the same box via loopback.
Most will also block all inbound ports except web + ftp, so you most likely wont be able to initiate a connection to your script from the outside to a listening socket script on the inside.
Also any cheap host wont allow you to run a headless script in the background for long, rendering any interesting php socket script useless.
Best of luck! Be sure to post your results.
