mpc acting strange

Yesterday I tried to copy few bars from one sequence to another and mpc was supposed to paste those few bars to seventh bar but it always put those in third bar. also one of my beats were partly corrupted. Two sequences of that beat were mysteriously dissappeared. Then I turned off my mpc and back on and loaded up this screwed beat and other one of those "dissappeared" sequences were there. but when I checked other sequences and came back it was gone again. WTF? This was the first time Ive had problems with my mpc. Have you guys had this kind of problem?


and I havent been drinking or smoking lately.
