My game crashed!

[Ekenna]

Hello!

I need some help. I was checking my game on my computer, when my computer ran out of battery. I restarted everything and when I opened my game, I lost everything. In stead of by big city from level 12, there was suddenly nothing.
What can I do? How can I get my game back?

Thank you!

are you back to level 1 or airport city does not open at all ?
