It's trying to log an error message telling you that it's having problems talking to the station. You'll need to reset the station - remove batteries and USB cable. Note that version 1.9.3 is now the current version, and I did some changes in that which hopefully stop it crashing in this situation, so it should successfully flash the error light.

Thanks Steve your solution worked perfectly.
