They seem to have tightened up on this recently, though I believe they still will give credit ( they tell you the request will sent for approval) if they restuarant is listed in the current book.
In your case the situation may somewhat slightly different since the restaurant left in January and the current books run Feb to April.

One thing they do see to be more stringent about are the places donated www which have some invalid days (usually weekends) or even those that require you make a valdated on-line reservation since the book says " visit our web site or call member services.." they refused me credit even though the week-day I dined would have been an eligible day when the restaurant was still in the program.
