Plus net is not allowing me to open safari on MacBook Pro 10.5.6 snow leopard

Hi

Plus net is not allowing me to open safari on MacBook Pro 10.5.6 snow leopard.
I very nearly missed an interview this morning because I had to find an Internet cafe, I'd really appreciate some help, all that happens even after going through network setup assistant, the page opens then the beach ball of death appears and I have to force quit the program and restart the computer by pressing the off button.

What do you suggest?

Thanks

A little more information would be helpful - like what year is your MB Pro, how full is your hard drive or how much is free. Have you run disk utility lately to repair permissions and repair disk? Have you tried resetting Safari?

This is an older version of OS X, as you know. I am not sure but this could be an issue?? Correct me if I am wrong but Plus Net is an internet provider - right? How is it not letting you open Safari?

And OS X.5 is Leopard, not even Snow Leopard. As Lisa points out this is a very old OS and may have problems connecting to WPA networks.
