Samples not working properly on standalone!!!

I have a big problem on Live standalone 2.3
My samples not working properly on every project.
I put some long samples on drum programs, fix the beats and sync, record them on sequence and all works fine until I record the project and shut down and then as I reload them the samples just play two bars and half instead of the original 8 or 16 beats.
It's always the same length, 2 bars and half and then silence.
In every project.
WTF.
This destroys all my work.
I tried to erase the samples, reload them, same result.
I tried to clear the tracks and make them again, same result.
That's a big problem for me.
I need help.

How do the samples look in the sample editor? Have you checked them out on the PC to see if the data is gone, or is the MPC loosing the data somehow?

On sample edit the sample plays perfectly and loops accordingly so its loaded prooerly on Ram.
Someone on GS told me to switch off Instant Track mute from preferences.
I don't see the correlation but i give it a try.
Crazy situation

SOLVED!!!

Dan from GS:
"Switch off Instant Track Mute. the instant track mutes are tied to the first track right now, so if an event doesnt exist past the first measure in the first track, they mute. it's an implementation weirdness held over from I think the MPC 2500. It may be different in 2.4, but that's what fixed it for another customer recently."
