Unhandled exception. System.Xml.XmlException: '.', hexadecimal value 0x00

[kurayamiblackheart]

crash on some specific sporecasts.
eg: sporecast ID 500222513793

SporeDownloader.exe sporecast 500222513793 results in:

Unhandled exception. System.Xml.XmlException: '.', hexadecimal value 0x00, is an invalid character. Line 164, position 14628.

other sporecasts seem to work fine. maybe it cannot read specific characters that are out of the charmap table it is using? I don't know...
