Hi, We've had this problem time and time again with IE and login problems to eBay, Hotmail and other sites that increased encryption from 2.0 to 3.0.
Even if you restore defaults the SSL encryption resets to 2.0.
Try the follwoing and see if it resolves your issure:
Control Panel --> Internet Options --> Advance Tag --> tick SLL 3.0 (default 2.0) --> ok and try to login.
The SLL 2.0, 3.0 and TLS 1.0 options are towards the bottom of the list, hope this helps.
