OK, I see.
IMHO the data of your *.dwt ist corrupt...?
So I would make a wblock, and then a new *.dwt.
ACAD does find the object by "_qselect", but it's not selectable. Funny and #§$%*%&$§#!
I do not like OLEs. Maybe you can trace the logo of your company and insert it as a block?
Maybe another experts do know more...
