Narrative:
Aircraft #2 was landing ach from the west. He was descending from FL390. I issued a clearance to FL200 and expedite through FL290. Aircraft #1 was heading southwest climbing to FL380. I asked him to expedite through FL350. I then turned the aircraft #2 20 degrees right and aircraft #1 20 degrees right. The conflict alert went off and I turned both aircraft 40 degrees right and told them to expedite. After reviewing the tapes and 'mcass' it appeared that both aircraft flattened off the climb and descent. The radar was also not receiving mode C prior to this.
