There was indeed a separate Module Disk with BibleWorks 7, but that included files for resources like BDAG, HALOT, and others. Foreign language bibles, such as Polish, were included with the program. The solution would, indeed, be to run the Setup program again. There will be a point in the setup program where additional
cutfullprice versions and resources that had been omitted the first time could be clicked (selected) so as to be installed. If any of the disks were not included in the first running of the installation, they will be called for when the setup program runs this second time.
I hope that this serves to be helpful.
