Woah, thanks TIG.
Next time I'll try not to destroy the space-time continuum

Yeah, I don't know what happened ><
Don't bother, the piano is the only thing I can rebuild without problem, as I have the measures.
Okay, I found the component which was causing trouble.
I was adding the black notes to my piano model and I think a black note is causing trouble.
Adding this particular component gives me the problem.
If you can find a way to fix it, here is the model, if not, it's not that bad as I got my other components back.
@Dave :
I was moving a part when this happened so maybe it went 10000000 miles away, so yes.
Zoom Extents get the origin (when I manage to get it) to the left middle.
I can't post the file, it's 5.7 Mio and I can't post over 4 Mio
Everything is on, but I'll try to add the components in an empty SKP
If I select all, it says that i selected 7 entities, which are my 7 components in the model.
I can share it if this can help.
I don't know where to found layers, styles, model statistics, outliner, sorry -_-'
EDIT : Found them, and my components are here, but can't be displayed 
Hello to everybody, I'm ManuHeel.
I've been using SketchUp for 3 or 4 years now.
I was adding the last things to my model when moving a part led me to nowhere, and I can't find my model anymore. I searched in forums for a solution but I didn't manage to fix this, I tried Zoom Extents, but nothing came up.
I can't see my model, I can't see the axes, sometimes I found the origin as a dot, but I can zoom as much as I want without finding my model. My last backup is also in this state.
Please help me, I lost all my work 
ManuHeel.
