Help!!!!!

I have a 1998 Honda Accord Sedan LX. (4 cylinder) I'm attempting to lower my car tonight. I've worked on it for 3 hours so far with nothing done except the strut and spring assembly removed from the car. THE PROBLEM IS:

I can't seperate the the spring from the strut. There's one bolt on top of the strut that won't loosen.

Yes I do have a spring compressor. I've tried to compress the spring 3 times already. I am installing Eibach Sportline Springs using my factory struts. PLEASE HELP!!!!!

I need this done by tonight because I need the car in the morning.

Thanks.

Hmm, it would have been so much better and easier had you purchased new struts with lowering springs. Eibach pro kit with OEM struts, not good. Eibach Sportline with OEM struts... really not good.
