Okay, based on working with people who had problems with BootSkin 1.05, we have put out a version 1.05A. If you have previously had problems with BootSkin, please try this version and let us know if it solves your problems.
BootSkin is a program that safely lets you change your Windows XP boot screens. The problems we've been mentioning actually highlight BootSkin's safety -- no matter how badly a boot screen is made, you can always get back to Safe mode and recover. By contrast, other boot screen programs patch your Windows XP kernel and if something goes wrong there, well you can imagine. BootSkin doesn't modify any system files. Instead, it takes the form of a boot screen driver.
