Since you can't forward your ports and get unfirewalled, you will continue to get that error. Sure, you can still download and upload, however you can only download and upload to users who are not firewalled. Usually this won't matter, but I have seen some shows where all the users are firewalled and so no data gets exchanged.

You may want to check out the Snail Mail forum and the Vines forum. Those forums do not involve downloading/internet use and are a great way for users to get new shows also.
