Can anyone help?

My nextgen keeps losing the settings and I have to set it up all over again. It seems to lose the settings randomly. It could day a few days of use or just one day. Seems random.

I am using the latest Pongo skin. here is what I tried:

Uninstalled nextgen, deleted save folder and reinstalled.... that didn't work
Then tried an older version of the pongo skin... that didn't work either.

Also, when I set the key beep to mute and exit and start nextgen again the volume is back up on key beeps. This happens every time... very frustrating.

Anyone else have these issues? Any ideas?
