I'm using windows XP, my computer is 6 months old, it is a 2.5 gb.

This is what happens:
I downloaded PT and immediatly, I was not able to log onto the internet. After 8 minutes of looking at thAT damned hourglass, I restored my settings to a few days earlier before PT.
Up comes the internet.
I reset it to receive PT, and again, can't connect with my ISP.
I've done this dance several times with the same result.
I sent a feedback note to PT, and they told me that they were being attacked by some hacker who was tying up their system.
I'll see if I can post their answer.
