btw kaoreii, in regards to firewall, you can just make your firewall let certain apps through. just open your firewall setting and go to program setting and find the tab that says "hero", "ragnarok" and "sakray" if i am not mistaken.
then on the side you should find a tab that says "block" or "automatic" just switch it to "allow". if not choose "trusted" or whatever word they use that means you want the program to be allowed to access the internet.
