Sparkfun ATTiny85 Programmer error message.

I got one of these programmers.

I installed the files on this page http://hlt.media.mit.edu/?p=1695 and the ATTiny options show up in Arduino IDE, but every time I try uploading code to the attiny chips I get this error message:

java.lang.NullPointerException

What am I doing wrong?

Use this (attached)

Don't use the master folder. Use what is inside of it. Good luck :grin:
