I screwed up, can somebody help me out.

[team39763]

I feel like an idiot for even posting this, but my brain ain't working right now and I can't figure out what to do.
I was installing my Moroso springs and using the Autozone spring compressor(the one that goes on the inside). I got everything done and was trying to take the spring compressor out, but I can't. I let the tension off the spring, I unhooked the upper control arm...nothing worked to get the hooks out. I know this is probably so simple, but I can't figure it out. My truck is a 82 C10 and the spring is about 3.75-4" inside diameter....the same kind of coils that have been on my truck for a few years now.
I'd appreciate any help or advice. I'd rather not have to pull the spring out to remove the compressor, but I will if I have to.
