New clutch linings installed -> nothing works anymore Ducati 1098

Hello, I hope here someone can give me a tip, what I did wrong or did not do. I have been driving a Ducati 1098 from the year 2007. The bike is really in shot, only the clutch was cracked strongly and squirted at almost every traffic light when driving. I had ordered new clutch coverings for this reason. Model was right, number, diameter and so on also right, so pressure rod pulled out, old coverings and discs removed and new discs and Composed according to manufacturer specifications. Pressure rod pushed on again and the 6 ultra-solid springs (in the Youtube video the person said that the springs are not very stable, which are built in with me abnormally stiff and even double springed.) screwed with the screws, while keeping in mind the screws nicely loose, so do not put on with much force. Clutch lid again on it and now came the big surprise. I pulled the clutch and nothing happened. I turned out the screws of the pressure plate again and tried to see if anything happens when the clutch is operated. Without screws and springs, the pressure plate moves (can you call it that way?) a little bit when the clutch is operated. However, if I press the pressure plate on the clutch basket with my hand, the pressure plate moves a little bit when the pressure plate is pressed. The pressure of my hand is enough to prevent domes showing an effect. One can imagine what the pressure rod and pressure plate can do against the pressure of the 6 bombastic springs. So, now I stand there, that the good Duc can no longer be driven, because maybe I did something wrong. Hopefully someone can give me a hint here, how I can get the good part back to running or to cupola. On the Kupplun This doesn’t seem to be the original clutch anymore. Do I have to vent the clutch hydraulics in order to get pressure on the pressure rod again? EDIT: I just found a problem. The 6 screws with which the pressure basket is mounted are already sucked out in the thread of the engine half. On some threads I can push the screw properly without power. That’s certainly not right. Can I do something? Maybe use longer screws? Or is it not recommended?
