pirates of the Caribbean - problem with save settings

[Panagiotis Salesiotis]

Hello
In my pirates of the Caribbean pinball the problem is it does not save the settings I make, like the free play, etc ... every time it closes makes a reset settings. there is no battery problem because the scores saves them normally. What it can be?

I change the small round battery but not working. still lose the settings

and/or reflow the solder on the battery holder?
