I have the game Rumble fighters and it stopped working saying that it can't receive the file index from the server. well i have done everything including reinstalling the game and such and nothing has worked. Everything else works with the internet as well and RF has always worked. I contacted the company and the only advice they had to give me was.
"Thank you for contacting our support team. If you are behind a router, try setting your IP as the DMZ host or forwarding ports 7000 through 8050 to yourself (refer to your router instruction guide for help). Please contact us again if this doesnt work."
but i don't know how to do this can someone please help me and put it in laymans terms?
