I have checked the file it is referencing, and it is definitely not a bad link (downloads just fine), and I cannot see any syntax issues with the crosstie, so how do I make this go away? It has been emailing me every day, and I cannot find an issue with the crosstie :S

Thank you for letting us know. We still have a few bugs in our CrossTie checking program, and we appreciate the feedback. We are going to turn off the nags for now until the system is running better.

Thanks,
Anna
