Site having trouble validating reciprocal links

[DirectoriesRUs]

I'm new but I must start by saying how impressed I am with the script.

I am having trouble validating reciprocal links on http://www.travel247365.com/ . I have had successful submissions but they have disappeared lately.

I tried on adding a couple of different test sites but continue to get the following error:
A link to http://www.travel247365.com/ could not be found at the specified URL

I found the fix in this thread {not available}
