Hotmail e mails…please help

Please help, I have spent all morning and got nowhere...I can gain access to my two hotmail accounts and messages via my blackberry phone though not through my laptop. I can access the accounts on laptop, though not open anything, its just buffering.  Why? I can tick boxes and move e mails though I cannot open any, or clear junk and deleted files.  Two days ago I was asked to provide a code to verify my account on one of them, which I did, now its seems I cannot work in either. Its crucial to my job that I have access!!!!  Traci
