what do you mean? The link to the .capx is there
Sorry, somehow read over that.
It looks like the actual project is missing...
See this (sorry for German language. "name | size | packed size | ..."):
Usually, there is a [projectname].caproj and [projectname].uistate.xml in there too.
Those two are missing. Everything else is there, animations, event sheets, ...
I have no idea why that is. Maybe a anti-virus program thought that might be a virus, no idea.
Anyways, let's go on how to fix this.
I'm in no way capable of interpreting the.caproj and .xml 100% correctly, but it looks like it's just two xml's with project info, nothing relevant.
I'd say what you can try is to create those two file manually, fill in what you know or remember of your project, add the two files to your .capx and try to open it again.
Here are the file's contents with what I extracted from one of my projects:
Create the two files from scratch, paste my contents and edit it to your project's information.
Remember to name the two files accordingly.
Since you need the plugin's names and id's of the plugins you used in your project for the .caproj, you might need to ask the plugin developers for help there. Or you can try to find those two values by searching in the .js files in the plugin's folder.
If everything fails, you might wanna call to Ashley , maybe he can help you with reconstructing the two files.
(All assuming that those two files are the only things that are missing)
