I can’t access my contacts when i want to send an email.

I had this problem last week and it was temporally fixed but the problem is back. I check all my settings (HTTP) to no avail. I'm supposed to access a list of choices when i type the first letter of the contact but all it does is spin and spin. No matter what computer i use it's the same as my personal computer. I'm sure it has something to do with Hotmail and not my settings. please help!!!!
