When one of our customers installed Office 2013 on one of their PCs they suddenly could no longer get the Holiday Scheduler to function. Thanks to some investigative work by Chris Quick of Crusade Computer Solutions it was discovered that in Excel 2013 there is a limit to the number of characters in the file name. If you go above  31 characters the file will not function properly and any macros will be disabled.

At MTIS we will re-name the 2014 files with shorter names to help avoid this becoming a problem.
