Thanks Virginia.
Jim,
I deleted the \The Master Genealogist v7 file found at :C:\Documents and Settings\All Users\Application Data and when I opened TMG the dialogue box indicated it was rebuilding a file but the F1 button, the Help and Help Contents are still not accessible.
I emptied the trash, shut down, re-booted and repeated the process with the same results. When I say not accessible, I mean when I press the F1 or select help or help contents - nothing happens.
What now?
Sheila
