Error upon loading game...

[TheSinHarvester]

New to PS2 and was playing for a few hours yesterday with absolutely no issues. Have been trying to play all morning but whenever the game is trying to load up it crashes and opens my browser saying an error has occurred with the game. I've tried loading up the game probably more than 10 times now and it always loads to about 75%-80% and just crashes. Is anyone else experiencing this?

EDIT: Never mind! Found out it was my firewall blocking the game.
