firstly, I'm sorry for my weak English and also I'm sorry for non-windows VBoot question

I know you don't have enough time for support your old products, but I want to know there is a chance for repairing VHD by myself!
I have installed Ubuntu 9.10 on a VHD and using it for compiling my apps, a day it hangs and I have to hard restart my laptop but after that it couldn't boot again and also VMLite couldn't open or boot it. Now, I'm using Ubuntu 10.04 and it's great but today I try Ubuntu 9.10 again and after completing install and when it was in its 'idle time' I start to moving mouse but it hanged and again it couldn't be booted!!!
I attached the screenshot for error message.
Can I repair VHD file?
