Help! 230SLK repaired roof cylinder, now that works but trunk won't open nor roof

[AlexSLKN00b]

So, I just bought this beautiful gem recently. And the roof was working... Yes, but of course, he didn't tell me on the long drive that what was dripping when I closed it was hydraulic fluid onto the passenger seat.
Sure enough, it had enough fluid for it to work like five times, then the last time it took forever to close, you hear it trying, and the roof BUTTON GOT HOT.

Well, sure enough, I learned to check for fluid; it was down to like 1/5th.

I ordered the O ring set, the fluid, and spent all day Friday working on it. Job done! EXCEPT... When hit the button, the pump starts working, the rear windows go down, the roof UNLOCKS (no liner so I can see it) and that, my new friends, is IT. I the bottom stays lit as long as I'm pulling on it and I can hear the pump working working working in back, but nothing happens.

Most noticeable, the trunk LID does not open at all.

I've covered the basics, but I am left with questions like... did air get into lines where it shouldn't have (I still have no real idea exactly how this system works yet), did I burn something out? It was working fine and now nothing.

I understand there are many things to check, and have spend hours scouring, but I can't seem to find a scenario like mine where dashboard shows no errors I can see, the button is not blinking weirdly, and where all of a sudden now it UNLOCKS but nothing else happens.

Can someone PLEASE help before I lose my mind???
