Hi Carolyn - sorry to hear you fell for it too - there are instructions on how to restore the file with Windows 98, have you tried them? I found some on this link - in case the link doesn't work, I'll post the instructions.

1) Click START - RUN, type SFC and hit ENTER
2) In the "Specify the system file you would like to restore" field, type C:\WINDOWS\SYSTEM\JDBGMGR.EXE and hit ENTER
3) In the RESTORE FROM field, type in the path to your WINDOWS CAB files
(ie. C:\WINDOWS\OPTIONS\CABS)
(ie. D:\WIN98 where D is the drive letter assigned to your CD-ROM)
4) Click OK and continue with the restore function
-- End Windows 98 Instructions --
