[SOLVED] Can't subscribe to a specific calendar

Hi. I've tried subscribing to a number of calendars. They all work fine except the following:

http://www.ecb.co.uk/fixtures/ICSExport.ics?t=2

which reports "Calendar Subscribed Successfully" but then isn't listed.

Is anyone able to tell me what the problem is? Thanks.
