About to give up (Help with Intrax lowering spring install)

[RoRo]

I'm attempting to install my Intrax lowering springs, which I originally bought for my first Aveo back in 2005. I've got both of the spring compressors on the right rear spring; however, I've never done this before and I have no idea what i'm doing. I don't want to pay a local shop $80, if I can do this myself.
Here's where i'm at now:


It seems like i've got both sides of the spring as compressed as it is going to get; however, I still have no wiggle room to get the spring out of there. Am I completely messing something up? I did a search online and on the aveo forum and did not come up with a how to on installing lowering springs. Can someone help me out please!!
