My copy of CrewCheif refuses to update ..I am on 4.9.8.3

Every time I open CrewCheif it wants me to update, the files download fine, I run the update and I am still on 4.9.8.3..it is a never ending cycle

I have deleted and downloaded Crewchief several times now, but still on 4.9.8.3

Would appreciate some help with this ..

Thanks
