mpc ren issue .... sequencing wont play back

ok so I make a beat in mpc software .. save it and reopen it as a plug in in FL studio 10 to add some more to it with the vsti in that program . I save everything in both programs . I actually play the sounds I want and record them in Edison , then save them and load them on to a pad in mpc ren . so I can open the project in the ren. standalone version and still have the sounds and scores I played from fl studio . but some songs when I go back to the mpc software , they wont play the sounds . the sequencing is still all there and the sounds are there and play when I hit the pads . but when I hit play / play start , nothing can be heard ... any idea what im doing wrong ? I am fairly new to the renaissance ... but been on fl studio and the mpc hardware line for years.

So the new sounds you have made in fl studio you've recorded into edison and saved them as loops... Then you open them in mpc software standalone again and trigger them from there? Are they the sounds that dont play? or the old ones(From when the mpc project was first started pre fl studio) ?
