Are you sure you didn't delete the .hdd file instead of the lock file?
If the hdd file is corrupted, using the Windows CD for repair won't help it since the file is rendered unreadable.
Do you have a backup of this file?
You can create a new VM with XP from scratch in PDM 3, you don't need to upgrade.
Also, I have XP on PDM and never did Windows crashed on shutdown, I know it's considered popular/'normal' for Windows to crash, but really, a VM is a controlled environment in terms of hardware, there's not much that can cause a crash.
