Why is Puzzle Pirates closing my browser?

I’m trying to install and play Puzzle Pirates, but every time I click on the icon for the installed game, it doesn’t open. The hourglass appears for about 2 seconds and then disappears. When I try to play from the website, it closes my browser (Firefox 1.5.0.8.).

What the heck’s going on? I can’t find anything about this on the website’s forums, either. Any Puzzle Pirates onboard? Arrrr!

Did you try emailing for support? ( support@puzzlepirates.com )

Also, from the installation page:

What’s the likelihood of this being a factor?

I’ve now emailed support.

Virus protection isn’t a factor. I turned it off to install the game.

There’s also a technical issues forum on the official forums - it might get you a faster answer if one of the other players knows the answer: http://forums.puzzlepirates.com/
