When you see that message that Construct cannot open your file, press F12 and check the errors at the bottom of the console log.

"[Project] Exception opening: File format is not recognized."

is there something i can do?? The file format is a C3P.

Try opening it in beta version of Construct:

editor.construct.net/r324

If it doesn't work, make a copy of the file, rename its extension from .C3P to .ZIP and try opening it with Windows. If Windows can't open the archive either, then there is probably nothing you can do.

it also says that the file has 0 KB. That means that the file is empty, right?

Yes, unfortunately.
