#21 Unable to read calendar.ics

[XB-70]

I exported an outlook calendar to calendar.ics
Upon trying to import, into Mozilla Calendar I got:
Unable to read from file: D:\....\calendar.ics
[Exception..."Component returned failur cod:
0x80004005(NS_ERROR_FAILURE)
[nsIScriptbleUnicodeConferter.ConvertToUnicode]"
nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS
frame :: chrome://calendar/content/importExport.js ::
convertToUnicode :: line 98" data: no]

I clicked 'OK' and it seemed to import most everything
(I'm not 100% sure).

NOTE: I did NOT include the file in question due to
confidentiality concerns.

Thank you in advance for
a) your time in developing this wonderful piece of
software which is helping to move me off MS
b) you time in dealing with this issue
