If you use any kind of computer program to make layouts and pre build guitars such as eMachineshop and such. Make sure to back your stuff up on a separate drive or flash drive. I had the unfortunate event of hitting the dreaded blue screen from a registry error. Luckily, I could get in through safe mode but I had over two months of tweaking and building and fine tuning guitars, amps and other things that I almost lost like that. So, friends, please back your stuff up. I can't tell you how much I would hate for you to experience this anxiety I did for a few hours last night. Catch you later, Bill & Ted.
