Can’t access my email since the upgrade to my hotmail account.

My account has changed to outlook with a blue interface rather than orange, when i enter my account i cannot see my emails listed, I can see my folders on the left but the middle where all recent emails should be displayed is all blank but if i scroll down i can then see them but then cannot click to open my emails also the feature to switch back to hotmail is not available, please help? I did not upgrade my account and if it was going to happen automatically then it should work without any issues? Please help.
