We have been having F/E Problems with reports and Allen Landry Suggested that we check some fields in BKARHINV to make sure that certain fields contained the correct information.  However, I am unable to do that when I go into File Maintainence and choose BKARHINV
I get the following Error  
 
Btrieve Status 35  The application encountered a directory error Key (G:\DBAMFG98\BKARINVT.98 DBIERR_invalid directory  
 
How do we fix this
