Foobar Customization issue (.9)

[kaluminati]

Using .9 and I've been trying to replace the standard buttons with new ones I downloaded of some customization sites. It works fine but whenever I close and reopen foobar, the buttons are missing, and there is nothing in their place. I have to go back into the button customization and apply the same button .png or .fcb again. Has anyone had this problem?
