I feel like RF is like a childhood friend that has no more friends but you.You have already moved on but you feel bad and guilty of leaving him all alone with nobody to be with him. Im trying to see my friend but im having soo many technical issues idk when i started playing but it was around 2010 ogp. I really hope that this company can do something to bring back the old players,cause i kinda miss this game and want to have some fun again. Idk what im talking about but this is whats on my mind.
Antivirus is a common reason, check if your firewall is blocking rumblefighter and gameguard, and let their files in the firewall. Or right click rumble fighter client open file location find Rumlbefighterlauncher open that Restarting computer can help too
