Photoshop CC... file not opening?

So, I started drawing out a picture on photoshop... I saved it as a photoshop document and closed it all up. The next day when I try to open it all up, it refuses to open! There is an error message that says "it is not a valid photoshop document"

I'm wondering if it's some kind of error with the free trial, because that's what I'm using right now? But I've made sure, and it IS a photoshp document. I don't know why it's doing this. Please help asap. :(

or:Try to find out that the Photoshop file is ok or not? See the extension as well, I dont think this error is showing because of trial version. Check out the file again.
