why is my ACT HDSS clutch slipping?

ive put about 9000 miles on this clutch with no problems until tonight. the slipping was horrible... worse than my stock clutch. was it maybe just temporarily overheated? or does it need to be realigned? the clutch was the only thing i paid somebody else to do - and the flywheel at the same time. so i dont really know what im doing here. the clutch is stated to hold up to 41% over stock torque..which would give me up to about 200 ft. lbs from my stock 145. theres no way im pushing 200 with these mods. help?
