Composition window doesn't work

[default81tvqginxkxx]

Hello!

When opening after effects, I can't visualize the composition, making it impossible to edit in that area (attached an image for better understanding)
I tried uninstalling and reinstalling the program but it didn't help. 

Thanks!

The crammed nature of your screenshot alone is likely a dead giveaway: Your system does not meet the minimum system requirements (some laptop, presumably) and thus hardware acceleration isn't working at all or not correctly. The standard steps apply: update your graphics driver, check the relevant settings in AE.
