im in the temple of the spider....i got up the final elivator...i got to the place where i should put the crystal and revive the temple...but...it seems that i dont have the crystal...i lokked at a recorded walkthrough...and i saw that all i should do is just put the crystal by pressing "E". as it seems...i dont have the crystal....i cant put it there...

so what i tried to do is to download saves from the net...
i put some of the saves that i thought they were near to the point i got stuck...and i saw some saves with places that i have never saw and realy dont think those are the im looking for...i from the "temple of the spider" to "fire in blood". to something that looks like a goblin fort...there was an orc prisoner i couldent release... aboce all this shit...i looked at the objectives, and there is none!(and i lost all my SP and staff)

so can someone tell me what i did wrong or give a save with proper equipment or to tell me what is the following save to the final save of the "temple of the spider" i mentioned... plz
