This happened to me once,and what I had to do was re-download the bootskin from the web.The ones stored on my external hard drive would not work.
Yeah tried that to with all 3 versions but it didnt make any odds.
BUT ANYWAY I'VE SUSSED IT OUT AND FOUND THE CAUSE. Its a very technical reason.....LOL
My PC has 3 HDD's in it, one is partitioned down the middle so i have 4 drives to view in total in 'My Computer'.
A few months back (but after/since installing BootSkin) I installed a new 2nd operating system on my machine that being Vista. I installed it as OS2 (secondary OS) on one of the partitions on the drive that is partitioned down the middle.
If I booted normally XP loaded, or I could pull up the boot menu from bios and choose to boot from Vista.
I then chose to 'sack' Vista (got it on another machine) for the time being and free up my drive. Thats where the problem started (without me knowing).
What i should have done to free up that drive is format it from XP but instead all I did was highlight the contents (ie Vista's windows, program files etc) and right click delete (send to bin).....Bad move on BootSkin's behalf.
What that done was empty my drive but left it as a 'System' drive and not logical partition, thus leaving some hidden info on it regaurding 'Boot.ini'.
So when booting, BootSkin was having trouble due to the fact the machine was seeing more than one bootup drive/OS so obviously causing the problem.
What i did to sort it was simply change the drive from a System/Boot drive to a logical/storage drive with Norton's Partition Magic, but im sure the simple Windows disk management could also do the trick.
So in a nut shell, BootSkin does not seem to work on a system with multiple OS's, or any trace of 2nd boot/system drives installed on the machine.
What can be done if you are using an OS2 is before using BootSkin, unplug the drive with the 2nd OS on it from your motherboard (switched off machine obviously) boot your OS you wish to change the bootskin on, apply the skin with BootSkin, reboot to check its there, switch off, reconnect OS2 drive, now the bootskin you applied 'should' stay with the OS you applied it to.
If you have this problem and need any help feel free to 'question' me.
I'll check back now n then even tho im sorted, coz it seems like im the only one who knows all this coz i been searching on this forum for days about it with no luck.
Please post to let me know if this was any help to anyone at all, i hope it is.
