The reason is a date format mismatch. Until this problem is solved, there is a workaround: 
- open the XML file with an editor such as Notepad ++ 
 
- locate the following line: (should be the 3rd line from the top)
      fileHeader companyName="STW" productName="RAMView" productVersion="V1.09r6" creationDateTime="2011-09-12T8:31:41 AM" 
- make sure that the time format complies with the following format:
      hh:mm:ss
      (if necessary, add a "0" to fulfill the 2 digit format requirement) 
- make sure the line does not contain "AM" or "PM"
