Linq2Twitter stopped working

I'm doing a simple search using Linq2Twitter:
var twitterCtx = new TwitterContext(singleUserAuth);
            var results = from search in twitterCtx.Search
                          where search.Query == SearchString &&
                                search.Type == SearchType.Search &&
                                search.ResultType == ResultType.Recent &&
                                search.SearchLanguage == "en" &&
                                search.Until == date.GetValueOrDefault().AddDays(1) &&
                                search.Count == 100
                          select search;

            Search srch = results.Single();
This was working fine a week or so ago. But now when I try it I always get zero results. No errors. I've tried different oauth keys from different users, but the result is always the same.

Never mind. My mistake.
