I ran your script and had the same errors that Quartus II was giving me. here are three of them:

usually the LEDs and 7-segment display turn off and the LCD stops scrolling. I will also ocassionaly get an error that says "java.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log is being created."

Any ideas? Is this a USB Blaster problem? thanks for all the help!
