Outlook/Hotmail Issues

Hi,  current hotmail/outlook user experiencing serious problems at the moment. Can't access any folders, won't let me open any E-Mails and won't allow me to access any other pages of my inbox. Never experienced anything like this under Hotmail so what's changed? Incidentally I can still access E-Mails from my I-Pad and I-Phone but it's on my laptop where my account was registered that I'm having the above problems.
