I'm not going to be of any help to you, but would like to confirm that I now also have had this crop up. You are not alone. In the past this has happened about once every six months and I have always been able to solve this problem by deleting the files in the FTW temp folder, as suggested by Info in knowledgebase #2287. Unfortunately this does not solve the issue now. FTW 16 just freezes midway in its web search process. I will post a solution if I can find one.
