Unless you actually deleted the savegame files, they will still be in the My Documents\LDW folder in your original Windows user account. You can find more specific instructions for locating (and backing up) the savegame files here in the Virtual Families guide.

Since you created the second Windows user account after Virtual Families was installed, you will need to create a new shortcut for it in the new user account. The easiest way is to open My Computer, navigate to C:\Program Files\Virtual Families, and right-click on the game's program icon (make sure you don't accidentally click the uninstall icon, which looks similar), then select Create Shortcut. Drag that shortcut to a convenient place, such as your desktop. You can also refer to Windows help to learn how to set up programs in newly-created accounts.
