DC Problem with Soldier Front!!

Hi, whenever i go to the ijji soldier front website sign in and then press play live i go in the game and go in the lobby but once i go in a room and press start i dc and theres this small window that says. you cannot open multiple soldier fronts (3).... can anyone help me fix this problem? ummm btw i didnt try restalling cuz i couldnt find the install icon but can only find the uninstall

press alt ctrl del aka task manager then go to process then end soldierfront.exe or related things to sf and than try it again. Tell me if this works.

ill try it soon and ill PM you if this works, it sounds like it works though and besides if its posted by you then there are 2 things im positive about
1. It works
2. I can trust you
