I've got EPG collector and guide hound all setup to provide the EPG data in Windows 7 media centre.  This is all working correctly to provide a weeks EPG guide for all the channels.
Part of trying to get this to work, I have recently enabled the series posters and those are now showing in Media centre, however I cannot get the Channel logos to show up.
In guide hound Configuration I have coppied the links to the images from the default file and pasted them in for each channel. 
I have checked that the links actually relate to the correct image and they do. 
I have tried downloading a few images to the channel logos folder and changing the link from a http link to file://C:\ProgramData\EpgImporter\ChannelLogos\parliment.jpg and the images still wil not show up.
Nothing seems to work.  I previously had this running on a different PC.
What am I missing?
