My korg M3 loses it's datat setting after turn off?!!

[DAR_2002]

My M3 loses the set data and global setting after turning off. Every time I turn ON my M3, I have to load the set again and edit the foot pedal in global setting even though I had saved the global setting before?!!

The battery is not the problem, I have replaced it 2 times, nothing changed.

I dont know if Im doing something wrong when I load the set. So please check with me my steps for loading a set, maybe Im messing or doing something wrong:

I go to media, go to set folder, open it, go to pcg file, load it, a dialog box will appear asking if I want to load ksf,sng,kge files too, I check them all ( some time the sng, kge files are not avilbe in the sets, so I dont check them, file path not found message appear, So I know that), also I check the option Clear, to clear all previews set samples.
then press OK. the set will load. and Done.

after that I check the set, programs are ok, combis are ok.

Did I forgot to do any thing?
Do I have to do something else after that to save the setting?

Thanks everybody

Sample data and sequencer data is lost when you power off. It can't be saved internally so you have to reload that every time.

Global settings need to be saved using the Write Global Setting menu command while in Global mode.

Other PCG data (programs and combi's) should be ok after loading.

Further to what Bald Eagle wrote, be aware that some PCGs may have Global Settings saved inside them and they may be different from your setup. You can check before you load a PCG by selecting the PCG file and pressing the OPEN button on the screen to drill down inside the PCG file to see what's in it -- you will see "Global Settings" if it was saved inside the PCG. You can also choose to load the individual parts of a PCG (programs, combis) if you want rather than loading the entire file all at once, which will avoid loading any saved Global Settings and temporarily overwriting your own.
