Computer crashed - now hoster is gone!

[prober]

My primary laptop that had my hoster set up on it finally decided to stop working in between gigs. I Had to go to my back up. In the mean time, I sent my laptop to Hewlett Packard for repair since on-line tech service could not do any good. (The laptop would show ac power and charge the battery, but was completely dead otherwise.) I specifically said that I needed my hard drive in tact because of the Hoster software. After convincing me HP would not harm the hard drive and charging me $298.00, my laptop was returned working, but they had reformatted the hard drive and all was lost. I have talked with HP twice and could get no help. They suggested getting in touch with MTU for help. (I told them I only had license for 2 installs.) Is there any help other than a new purchase? Right now I am limping on one laptop praying it doesn't fail.
