Why is my NeXus Client always flicking?

My client is always flicking... top left corner, it says "Loading - Please Wait" and disappears the next second, reappears, disappears, etc... How do I fix this? Its pissing me off, I just bought SorcGardenPro and can't run it because of this shit.

Thanks.

 

Hold S while rs is loading, I think thats how you fix it.

 

Thanks so much, it fixed it
