MPC2500 - JJ OS XL problems

Hello,

I have really annoying problems with my MPC since I've installed jj os xl.

for example. what if I save and load the next time wants the missing half of the samples and somehow even the chopped samples (which I have stored safely) are simply gone and I have to make all things new!

or if I want a project to save again, then the same project would save over the old one, is ne error message and I have to open a whole new folder and save everything for the 2nd time, which leads to massive amounts of storage space that I sd to my wasting card (or just delete the previous project needs, but not what should be the reasonable thing)!

or my cogs, I need to scroll rotates, and by simply going crazy. I have to adjust everything again and re-programmed, if I was still looking like this before!

I could go forever now so forth, but I hope that's not necessary!
As I said these problems, there is only since I've installed jj os xl ...

Hope someone can tell me how I fix this error without having to jj os xl uninstall the thing that has cost very expensive ...

Did you restart your MPC, keeping ERASE button pressed?

Try that first.

I've done that now, but since nothing has changed. what should happen

did you load JJOSXL from free JJOS? You jog wheel settings can be changed.
Hit MODE + PAD 10. there is the jog wheel settings, make it 1 instead of 2.
I have hundreds of projects all in there own separately named folders. If you name them then its easy to find later. Just the best way really to save stuff. Saving over your previous project will delete previous project.
