Getting data out of IPD files without abc berry

I need to extract my calendar from an IPD file. I have a bunch of dates that won't sync with Outlook, iCal, etc. It seems appointments created before a certain point an time are the problem. I can't even get those dates to appear if I sync to a text file. But the dates in question do appear on BB, and in ABC Berry. I wan to extract them, wipe my calendar and read them.

I don't want to spend $20USD on ABC Berry, as I'll likely only ever use it once. Does anyone know of an other utility that can pull appointments out of a IPD file?
