saving issues,ram, timestretch problem

hey guys i ran into a problem which was my fault .
let me explain i made a beat with two timestretched samples and i chopped another timestreched sample, made the beat everything was gravy, saved it all went to bed, only to wake up to see 1 of the samples lost its timestrech , and the chopped sample lost it as well...what i think happened was i saved everything prematurely then after everything was all said and done i resaved it forgetting to rename the samples so basically it never resaved those samples... now i cant even load it all because im still using 16mb of ram......basically what im asking is i want to correct the samples that lost the timestrech but i didnt remember what tempos i originally used...any ideas???
thanks

just take a piece of your sample and loop it to find out original tempo then time stretch it again to the beat of ur current track. Other than that use ur ears. if worse comes to worse scrap it and start again.
oh yeh and probably upgrade ur ram.
