Hi, I have been working on the Admin Beginning trail today and this afternoon I haven't been able to lauch the developer edition. It keeps taking me to a page where it says I have log into Salesforce first but I'm already logged in. I go ahead and log in and then I click again to launch and enter my developer login and it doesn't accept it or give any errors except that I need to log into Salesforce first. I'm a bit confused. I tried a different browser (tried both Chrome and IE) and tried clearing the browser cache. Thanks in advance for your help! 

Hello- 

Has anyone else receive this error when completing the challenge for the Approving Records from the Feed (Chatter Basics)?
