Error: saying needing updated ladybug

Hey,

I am a new user to grasshopper and ladybug, I followed all the instructions online and downloaded both honeybee and ladybug in order to perform a sun study for my roof design. 

However, my commands always pop up orange telling me that I need a newer version of ladybug, however my version should be already the most updated version. Also it was working initially and running the sunpaths, it is when I wanted to perform the ladybug sunlight hour analysis that it stopped working. I have attached my file below. 

Your help would be greatly appreciated.

Thanks !
