RECALLED SEQS ONLY PLAY ONE DRUM HIT

i think i have been saving incorrectlyi have been replacing prgrms, sampls, and seqs when i save and now when i recalled a seqs and the prgm i had a wrong file message when i finally got the prgrm to load i loaded the seqs and its only one drum hit but its playing the proper sequence with that one drum hit. i have recalled the seqs before in the past no problem. please i am new and i have spent many hours someone help me with proper saving and also if i can save my old seqs. PLEASE! the old samples are all there but the seq has only the one drum hit for each sequenced track. can i insert the proper drum hits inside each sequence in each track?

The programs in each seq. must match for each track
seq X track 1 program a
seq Y track 1 program a
When saving, create a folder, save entire memory to this folder. Next time you power up, load the folder.

i only have 1 seqs and one prgrm. it could b corrupted i just dont know for sure because i am still very new. i get wut u are saying about the prgrms in each seqs there is only 1 of each i checked mode prgrm and checked to see if the pads all had the rights samples in the right order and they do. and i am now getting a file missing error and i just tried reformatting on mpc and comp. wut is the kind of format it must have? and for the seqs can i just make a new drum kit using the same samples in the same order because its just 1 seqs and 1 prgrm but the prgrm is a big one.
