Diner Dash 2 will not open. It was working just fine this morning but now it does nothing. I click on the icon and nothing happens. I eventually noticed a new notepad document on my desktop labeled "logfile".
Inside it is:

And that's all. There's not even a referral code where one should be.
Any help?

Hmm...this is really strange! I've never heard of this happening! My first suggestion would be to uninstall, disable all firewalls/antiviruses, then reinstall the game. Maybe your antivirus/firewall blocked a program vital to running the game. Otherwise, I would contact PF support(there's a Support link in the top right of the page) and include that notepad message in the email(in the section where it tells you to put any error messages). Their support is usually really helpful and fast--they should be able to help ;)

Hope this helps you!
