Hi everyone, My Thunderbird yesterday - without doing any unusual chances that know of - went weird. Whenever I open the programme now it shows a completely different interface and I can't navigate back in any way to the usual calendar, email, contacts. It also seems to be frozen, because when I click settings it doesn't open any window. I have attached a screenshot of how it looks now.

Could anyone help me out on how to get back to regular Thunderbird? I am also a bit worried of losing all my contacts / calendar.

Let me know if there's more info I can give from my end. Any help very much appreciated.
