I can't see my campaign page and portfolios!

Suddenly I can't see my Ad campaign page and portfolios. Everytime I click on Advertising, it shows an error saying this page can't be found. It was ok until morning. Also I can't find my store on Amazon Seller Central App. Not sure what's happening. Amazon customer service is useless in the UAE. They don't help at all. I can't see how many clicks I've gotten today and how much money has been spent from my budget. SO ANNOYING AND FRUSTRATING!!!!Someone please help.
