It looks like there was a problem with the horse data uploaded to the servers last night.
This has just been corrected and the information is now available for download.
If your copy of TBE is showing a red HD symbol in the status bar, then you are advised to go to the Filters tab on one of your systems and click the "Not Loaded" label to force TBE to download the data from the server once more. If the data is successfully downloaded, the "Not Loaded" will turn into a "Loaded" message.
Apologies for the inconvenience.
