Plz help a rookie with Yahoo pool
 

I have Ubuntu 9.04. I am new to linux, so I have very little idea how to use the command line. my prob is that I have installed java 6 but when I go tp yahoo pool I can get into the lobby but whn I try to open a table I get the message to turn off popup blocker and I have done that with the same result. I have yahoo games as an exception in the popup blocker but still the same messege. All I wanna do is play pool so can someone help?
p.s.
I can't get any yahoo games to load

Hi, and welcome to LQ!

Allow me to give you your first lesson with the terminal (it's really easy!) ;)

Open the terminal, and at the prompt, type:

It will ask for your password. You won't see anything while you type it. Press Enter.

(You need more than just Flash- URE installs everything.)

Hope this helps.

I tried that but it didn't work. This is the messege that I got when I typed what you said to ubuntu-restricted-extras is already the newest version.
