UNO R3 ISP trouble (ATtiny45)

Ok, now I'm trying to burn the .hex file to the ATtiny and I'm getting even more errors. This is the beginning of what the hex file looks like (middle part removed):

:100000000BC225C224C223C222C221C220C21FC2E7
:100010001EC21DC251C21BC21BC219C218C200049B

:0C0A96007C00021E00CE74080401100257
:00000001FF

And these are some of the errors (I had to remove some due to allowed characters per post):

Am I even burning the correct file? The instructions on Instructables mention a compiled hex file so I figured that was what I was supposed to be burning to the ATtiny45. Here's the link to the Instructables page (if it helps):

At the very bottom (Step 16) is the link to the source code file. Thanks again for all the help! I really appreciate it!
