Frusterated

Okay so I am officially frusterated. I can not log into the course blog and I don't know how to do it. I keep trying to log in and a note comes up and says that the page is insecure and asks if I want to continue. After hitting Yes, nothing happen and it just goes back to the original page and my log in and password are no longer there. I first thought that my information was wrong so I requested my password and user name and after recieving an email with the information, it still did not work. I don't know what to do considering I am suppose to post to the course blog this week. This is one of the main reasons I do not like all of the different websites and technological devices used throughout this course. I do not like that I cannot log in and it may effect my grade. If anyone can help me with this problem I would greatly appreciate it. Thank you
