Since I am testing Salesforce, I can´t see my Developer Console.

The first message is "Loading configuration...". 
Then I read "Loading workspace...", and that´s all.
I can´t see nothing else.

My Internet connection is perfect, and I´m using Firefox and Google Chrome.

I don´t understand what´s happening.

Please, help me!

Thank you.

I'm using MS Windows 8.1 with Google Chrome Version 35.0.1916.114 m
I have a free Salesforce trial version

From the "My Name" menu I chose "Developer Console".
I get a new window Force.com Developer Console with the "Loading workspace ..." progress bar.
The progress bar gets hung at about 50%.

Any advice?
