Draco: By reloading i meant, reloading the computer, because sometimes it works, i unstalled it, and installed it, it's working but i can't make the brush that i had to draw
Rainbow: I meant the "Could not complete your request because of a disk error''

There are loads of different types of disk errors:
"Could not save because of a disk error."
"Could not complete your request because of a disk error''
"Scratch Disk is Full"
"Could not initialize Photoshop because the disk is not available"
(And more)

So, if Draco's suggestion of what to do doesn't work, you'll need to provide Adobe with the exact error message, and any error number code.

Reloaded as in just closing the program? If so, try completely uninstalling it, and reinstall it back and see if that fixes the problem. If it doesn't, you could always check the adobe official site to see if it has a troubleshooter guide.
