Errors in program, downloaded overhere.

Question

Hi, I am an absolute beginner in C# and I use Visual C# 2010 express.

I wanted to learn from the examples, so I downloaded the yahtzee-game from this site.
Unrarred the yahtzee-file onto my harddisk and tried to open the project from within Visual C# 2010 express. Then a conversion Wizzard start and converts the program into Visual C# 2010. It said it was converted succesfully.
Next I tried to build and run the game, but I got lots of errors ( see screenshot from the uploaded file ).

What did I do wrong?
