Poker Grapher Q

[PSW]

I am getting message when I start the program. It is:

"An unhandled exception has occurred in your application. If you click continue, the application will ignore this error and attempt to continue. If you quit, the application wil shut down immediately.

Index was outside the bonds of the array."

What does this mean and how can I fix it?

My graph is funky when I hit continue and I can't make choices on which poker sites to include anymore.
