We have had a report of a problem running HappyHolidays! on a computer which also has an old version of iPhoto Library Manager installed.  You may see warning messages such as the following in your Console output:

2006-09-25 20:16:16.173 HappyHolidays![1107] *** -[NSBundle load]: Error loading code /Users/username/Library/InputManagers/iPLM/iPLM.bundle/Contents/MacOS/iPLM for bundle /Users/username/Library/InputManagers/iPLM/iPLM.bundle, error code 2 (link edit error code 0, error number 0 ())

To correct this issue, please upgrade to the latest version of both HappyHolidays! and iPhoto Library Manager.   If a re-install does not help, try removing the Library/InpuManagers/iPLM folder in your Home Directory, and Log Out and Log In again.  We have tested HappyHolidays! here along with iPhoto Library Manager and have not had any problems.
