Itunes Problem

Hi,

When i start iTunes, it doesnt remember my settings, everytime i start it, its like the first time i use it

-Get all the info screens pop-up (even though i said 'dont show this message again' the last time i used it)

-Equalizer is always set back to 'normal'

-It doesnt remember my apple ID

I use iTunes everyday so its pretty annoying

Could this problem be related to BD ?

Also when i want to sync my ipod, i cant make a back-up of it....

This is a bigger problem then the ones mentioned before.

Regards Jon
