Chances to recover files by using a stub .vmdk file for the missing one are usually good. I hope it's not the first one, because this contains most data that make up the partition and file allocation tables.
Please run dir *.* /one > filelist.txt in the VM's folder to get a complete file listing, then compress/zip filelist.txt along with the small descriptor .vmdk file, and attach the .zip archive to your next reply.
