No iCal Events Import

No iCal Events Import

I exported my 30Boxes calendar to the iCal format (with all my events - not just private ones) and when I import the file into Zoho Calendar, I get nothing. It says my calendar was imported successfully but not a single event shows up in Zoho. I looked at my ics file in a text editor and all my events are in the file so why would it ignore them?
