Thank you both for the quick reply! It seems to have worked.
Now I get the error:

main.cpp.o: In function `main':
C:\Users\Robert\Desktop\arduino-1.0\hardware\arduino\cores\arduino/main.cpp:11: undefined reference to `setup'
C:\Users\Robert\Desktop\arduino-1.0\hardware\arduino\cores\arduino/main.cpp:14: undefined reference to `loop'

whenever I hit verify. This also has me stumped.
