Yup, it's a function that I used that is not available until version 3.5. Let me see if I can work around it and upload a new version sometime tonight. I am using TblGetItemPtr, and in the documentation for that function there is a workaround that I may be able to use.

In the meantime, you could upgrade your OS to 3.5 and it would work for ya, but I will try to fix it.
