Unable to access the hotmail sign in page

I have recently purchased and connected a Telstra internet toggle to my lap top that hasnt been used for ages, as i usually access my hotmail on my phone (so my account is active). On the laptop (windows supported) i now have access to internet but it wont let me go to the sign in page for hotmail. (there doesnt seem to be anything apparent as far as blocked sites in the settings, I am wondering is this some privacy or security setting that is on the computer? If so can you direct me to how i can fix this problem. Thanks in advance
