I have just finished doing AM-B for Fiscal Year-end Routine and UT-K-D to Recalculate Chart of Accounts.  My Financial statements are OK and everything else looks OK.  I also Consolidated Inventory Transactions.  Noting went wrong.  I am now trying to delete a few companies I had used for testing and can't.
 
I get "An error has occured while trying to open file - BKSYUSER.B12".  I hit OK and get:
 
"The field is unallocated or any array removed from memory BKSY.USER.COMP".
 
I can't find anything wrong but I can't delete the companies.  I have rebooted the server and still get the same message.

I am not trying to delete the Default Company.  i am trying to deletes Companies 75, 76, & 77.  I had already deleted Companies 65, 66, & 67 the day before with no problem.  The files BKSYUSER.B and BKSYUSER.BME (my company) are intact.  But a search says there is no BKSYUSER.B-2 or BKSY.USER.COMP anywhere.
