Anytime! 
I came here to find an answer to the problem with the BSOD... and I found that all the answers were like the one from Seabass. It's easy to see why BootSkin might get canned with this kind of problem. Users shouldn't have to change their bios to run the program, it could be dangerous if the end user doesn't know exactly what they're doing in there. However, I have yet to see a PC with the security option enabled by default, I suppose it could be on in some manufactured PC's like HP, Dell... Compaqs, who knows? (I build my own PC's) Newer motherboards have this option set to off by default and manufacturers instructions say to enable it once you have the operating system installed. This isnt the first time I've had this problem, I get it when there is a new service pack installed as well. So I always remember to turn it off prior to reboot.
When I got the BSOD after installing BootSkin and changing to one of the supplied skins... ACK! BSOD!!
I managed to get in xp by selecting the startup option "Last known good configuration" Which restored the default bootscreen.
I had to think a second and it occurred to me that the bios is protecting the MBR from Viruses and any changes to it would be seen by BIOS as an attack, which then halts the system. Well, incidentally XP has the bootscreen as part of the main system... why? Who knows? Seems a bit needless for that to be a part of the core of the system as its only a graphic. So we can't blame BootSkin for the problem, it works fine now. Just a bit of a pain to have to go through this to get it to work.
This solution may not solve everyones problem either.
GOOD LUCK!!
