Hello, after experiencing some problems with my computer I decided to clean install it. Now the problem is that when I attempt to open the client, the "server check / firewall" pop up will show up. This happens even when I have my firewall disabled. I don't have anything on my computer that should block it, as I just clean installed it. Might help: - Windows 7 Ultimate, 64 bit. - Installed via the setup. - No Anti-Virus (Actually I don't have any other programs yet, only MapleRoyals). - Drivers are up to date. - Starting the client as manager. - Tried to restart the computer. - Tried to restart the modem. - Tried to change compatibility mode. - I don't have any other LAN connections to disable, since I only have one. Thanks for your help ! SOLVED: Apperently it's a problem with IP that starts with 149. I contacted my ISP and changed it. I'd like to mention a special thanks to Egonics who helped me so much via Skype ! I'm glad to have him around
