My working space isn't open

Thank you David, 
i really appreciate your help
I tried to do what you told me but it still the same.... nothing show up :(

Howdy Dark,

Has your hardware ever worked correctly?  I ask because this might be an incompatibility with your monitor or graphics card.  So, let's rule out pervasive problems first.

Try this:
1) close and relaunch Photoshop
2) if you haven't already done so, trash your preferences as Warren suggested
3) click File > New and choose the default document size
RESULT: what do you see?  A white document on your screen?
EXPECT: if this works, then the problem could be specific to the PSD you're opening.  If this does NOT work, then you almost certainly need to update your graphics card driver or replace it.

Hope that helps,
David

Thank you Warren,
I tried but it doesn't work in my case :(

Have you tried resetting the Adobe Settings File?  You're on Windows, right?  It should be holding control, alt and shift when you launch Photoshop (command, option, shift on Mac).  You'll see a dialog box asking if you want to reset the settings file. 

Click YES and then open your document.
