In order to be able to give you an advice, I need to know some details. Please post a list of all files in the VM's datastore, either running ls -lisa from the command line (preferred) or a screenshot of the datastore browser window. Please ensure all files and details (sizes, time stamps) are shown. In addition to this compress/zip the VM's .vmx file, the .vmsd file, as well as all the VM's vmware*.log files and attach the .zip file to a reply post.
What's the size and free disk space of the current datastore.
