Anyone have problems with saving???

i had the original software that came with the MPC 2500, I have had 2 main problems with this. Sometimes when I go and put sequences together in song mode the MPC freezes. The second is when I save things sometimes they end up in stupid places and then it cant find the samples to load it again or only some of them???

I just downloaded the JJ OS will thihs fix my problems???

I've only recieved the saving problem with the jj os so far.... will save everything ok except the complete sample from which I chop... for instance say i sample a four bar sample keep and also chop it into 8 peices when i save into a new folder in root on the hard drive it will save everything and then when it gets to the four bar sample i get file write error and it doesn't save... although I've found a work around which is to repeatedly save without replaceing same files until it get the whole four bar sample this is kind of a pain in the a$$. Could be my fault though now that I think of it i never reformatted my hard drive after upgrading to 5.09
