Operating system : WinXP Program and version you use to access Google Calendar (FF3.5):

I'm developing a script (based on an existing vCal ASP.NET class I found online) to generate an .ics file. This file works perfectly when importing to Outlook 2003. When I try to import to Google Calendar, I get the following error:

Failed to import events: Unable to process your iCal/CSV file..

I don't know too much about the vCal format or syntax, but everything looks fine to me. I'll post the sample test calendar .ics below:

And the source for generating the above code is which is nothing but the mvc view::
