Susan: I read that your computer crashed and burned meaning you lost all your stuff. that is truly awful and I can only imagine how you must feel about it. I thought I would share something with you, and hope you don't think I'm preaching or being a smart ass. I don't know if you are aware but sometimes it is recoverable depending on the why and what happened scenario. That said you do need an expert to take a look for you and hopefully your budget allows for this, as their fees can be expensive.
Something similar happened to me a year or so ago and I lost all my graphic art files which was a disaster as they took hours to create and were part of my job at the time. My wonderful techie guy came and managed to recover most of them for me as well as fixing the issue and recovering other stuff too. I now have everything, including my Internet files, back up every night onto a separate hard drive so that if a virus or something gets into my system I will at least have backup copies of everything. My husband does the same thing with his home computer as he has lots of photography on his. The separate hard drive is a Godsend and it sits beside the main computer doing its job every night. Periodically I go in and delete some of the older files so that there is always room for the new stuff. These hard drives aren't so expensive and many of them have huge storage capacity too. They are so worth it.
Anyway I thought I would share my experience with you as it may help you to resolve your own issue. Good luck with however you decide to rebuild your collection.
