Cannot import logs of any type except Windows Event Logs

Cannot import logs of any type except Windows Event Logs

I can't seem to import logs of any type other than Windows Event Logs - I only have 2 Log Formats to choose from: Windows Event Log and Eventlog Analyzer Archive.  I have tried adding my own Log Format Name, but the import simply returns to the 'Imported Log Files' window with no results.  Has anyone had this issue?
