Just a word of caution so as not to unrealistically get your hopes up... While replacing the missing extents can at times work, nonetheless it is not an absolute fix in all cases! You have at least 6 extents missing and I suspect more then that, however can't be sure until you attach the "Windows xp professional.vmdk" or the vmware.log file. Also if the missing extents contained more then the create size of 320 KB then it becomes more problematic and greatly lessens the likelihood of full recovery however you might be able to mount the disk and attempt to recover some user data. The likelihood of having a working virtual machine is slim to none.
Otherwise if you don't have a proper backup to restore from you'll need to create a new virtual machine and reinstall everything.
