Model inside of Sketchup 8 project gone

[NewbieTechguy]

Hello.

I have built a model house in Sketchup 8 and suddenly the model disappeared. The transparent guidelines have also disappeared and no matter how much times i zoom out or zoom in, i can't find the guidelines or any sign of a model. I tried measuring the distance across my screen with the in-app tape measeurer and it recorded 0m.

Please help me i've spent 100+ hours on this model.

Thanks and have a Merry Christmas.

Laptop specs :
32 bit / 4GB RAM / Intel HD 4000 / Sketchup 8 (not pro) If there are any other specs you'd need to know just ask

Thanks again
