Hi,
The fop2 client must connect to the fop2 server using port tcp 4445, if you cannot get pass the one moment please is because that connection cannot be established.
So, you could have that port blocked, or not forwarded if behind nat
You might have a flash blocker or no adobe flash installed (on browsers besides chrome)
you might be using the latest google chrome with a fop2 version lower than 2.24 (try with another browser, or upgrade fop2)
Best regards,
