The Community Builder won't load for my computer.  I've tried it on either laptops and it's loaded fine.  In the past, I've had issues with logging in to different SF environments where I'll login and it will just freeze on the login redirect. 

I use the Force.com IDE so I've wondering if there's been some conflict with my Java environment?  There's other examples of issues but I wondered if there's some way to troubleshoot Community Builder.
