If it doesn't work, I recommend you to make a HAR-file and tracert and send it to Support Team or Anne Bonnie directly. 

Here is an instruction how to make HAR and tracert: 

1. Access Chrome -> More Tools -> Developer Tools - http://screencast.com/t/dXnNlwFTV8y6 

2. Access Network tab http://screencast.com/t/rRKZ9T9bsG

3. Try to access the game 

4. Do the right click on any line and tick Save as HAR with content http://screencast.com/t/gxsrje20g

5. Input the following command in cmd: tracert plarium.hs.llnwd.net Then make a screenshot of it. 

6. Send this information to our Support Team: http://support.plarium.com/ or Anne Bonnie in PM.

This information will help them to understand what is the reason of your login issues. I hope it helps you.
