Altera Monitor Program Compilation Error

Hi,

I am new to Altera and was trying out the tutorial downloaded from the website using Altera Monitor Program v4.1 with QuartusII 9.1 installed on Windows 7.

But I run into error "dirname: extra operand `files'. when trying to compile the source file using Altera Monitor Program v4.1. I tried a few fixes like eliminating spaces in directory path, uses a shorter path, reinstall the program, running as administrator...but it still gives the same error...

I've been struggling for a day...appreciate if someone can give a hint.

Thank you.
