No Battle Entry

[jazz20 1,181]

So recently, my account has been acting up severely lately. For some reason, I can't seem to enter any battles whatsoever. No matter what I do (make a new tab, restart my computer, etc.) it won't seem to work. This is the URL that always pops up when I join a battle. My bro played on his account earlier on the same computer and everything was fine. He was able to join a battle. However, I can't! Please help I really need to rank soon for various reasons such as that 70% discount on Smoky. Here, this is the URL that always pops up when I join a battle: 

 

Fatal error. Resource id: 10001988, resource version: 2 [securityErrorEvent type=securityError" bubbles=false cancelable=false eventPhase=2 text="Error #2048]

 

PLEASE HELP ME FIX THIS. THANKS FOR HELPING. NO TROLLS PLEASE!!!!
