Here's the fix...
** Make sure that \GMT is in the DOS path.
** Leave Grocerymaster and choose Disk Opertating System. (DOS)
** Change to the GMT\DB directory : CD GMT\DB [hit Enter]
type: set dlc=c:\gmt [hit enter]
type: _dbutil prostrct unlock gromst.db
You should see something similar to the following messages as the database is repaired:
Inconsistency: gromst last opened Tues Aug 09 21:45:48 1994
\gmt\gromst.d1 last opened Wed Aug 10 06:11:42 1994
Inconsistency: gromst last opened Tues Aug 09 21:45:48 1994

Inconsistency: gromst last opened Tues Aug 09 21:45:48 1994
\gmt\gromst.d5 last opened Wed Aug 10 06:11:42 1994
3 inconsistencies fixed
Then just log back in to GM and hit the spacebar and all should be well.
