Can't Acces Color Customizer

When I go into the Highend Theme Options and the color manager, I click “color customizer”, then “save changes”, then “Run Color Customizer” but it always takes me to the wp-login and after I login, it just takes me back to the wp dashboard. I’ve tried this multiple times and have tried in both Chrome and Firefox but nothing has worked. Please help me get into the color customizer.
