Error_game_js5connect - Unable to connect to update server [HELP PLZ]

[D C]

Im currently at school (TAFE)

And trying to get on Runescape but always getting this error when trying to Load the Gamecode.
_______________________________________________________________
RuneScape was unable to connect to the update server. This is most likely caused by a firewall blocking the connection.

To resolve this:

If you have firewall or security software installed, they can often block RuneScape from accessing its servers. Please ensure that RuneScape/Java can connect to its servers on port 43594.
Note: Windows XP Service Pack 2 has built in firewall software. If, when loading RuneScape, this asks if you want to allow the connection, you need to say 'yes'.
If that doesn't help, then an external firewall may be causing the problem. Please ask your network adminstrator/ISP to open port 43594 for TCP traffic so that RuneScape and Java can run correctly.
If problems persist, please refer to the Technical FAQs, which can be found in the Customer Support section of our website.

If you're on at school, they most likely have a firewall blocking you. As it said, and since you aren't an administrator/have the admin account, you can't delete the firewall. You will have to stick to playing runescape at home.

Ahahaha, I had this error way back when.
I had to reinstall my OS to get rid of it.

I remember this happened to me a few times on my computer, I just restarted it and it worked fine, but seeing how you are on a school computer I don't think your going to get anywhere to far.
