hey man, glad your here but sorry to hear of your troubles... Im far from an expert in this area, but one thing i can suggest is:

try ticking that box and running it again.. If that doesnt fix it for you try working through this:

if that doesnt work, then hopefully someone with more knowledge will be along to help you further, there are some good eggs here
