Barry,
What you suggested (removing the cookiejar.xml file) worked. I went ahead and attached a .jpeg though to further illustrate my point.
I understand that it may be Google screen, however users are being (or were previously being) directed to use it (through the main log in screen) in order to access the 3d warehouse &/or the Extensions warehouse because trying sign into them through their respective windows (windows>>3d warehouse or windows>>extension warehouse) doesn’t work due to authentication issues if I remember right?

Anyway my problem is now solved, thanks for your help guys.
