Problems logging into Norton account and secure online storage

Hi all

I was wondering if other members have had similar issues that I have experienced logging into my account, or if the issue is in relation to my account only.

When I log into my Norton account via a browser, the browser ceases to process (after entering the correct passcode and secure code). This issue occurred on Windows 7 (Chrome), Windows 8.1 (Chrome and Internet Explorer) and iPad (Safari). However, from time to time, I am able to access the account on the Windows 7 and Windows 8.1 machines. Would you recommend any changes to setting on those machines to eliminate log in issues?

In addition, for peace of mind (given that I was unable to reach the storage despite correct password and secure code), is it possible to determine time of log-ins to the online storage or whether any files have been downloaded?

Thank you for your comments in advance.
