First port of call is to slap them for using Frontpage in the first place. Then do any of the above.
Also, how did they use FP? If it was just as a code editor, Notepad++ is a good replacement. If it was as a WYSIWYG, then DreamWeaver.
If they used it for it's proprietary database connections and data displays, then kill them. With nukes. From orbit.

Fairly sure it was for WYSIWYG but doubt there is money in the budget for a copy of dreamweaver at the moment.
