It looks like the latest files are missing. The virtual disk which I assume has a provisioned size of 5-6GB consists of 3 data files, from which 2 are missing for snapshot 000005 (Windows XP Home Edition-000005-s002.vmdk and Windows XP Home Edition-000005-s003.vmdk). Unless you have them on some backup, your options are limited and you may need to revert to the latest snapshot whis is dated Mar, 2012.
The descriptor file Windows XP Home Edition-000005.vmdk (a text file) will show which files make up the virtual disk (the snapshot disk in this case).
