CAP won't open anymore

I've been working on a little Jump'n'Run engine in Construct and saved very often with different filenames.

Now the last bunch of cap files won't open anymore. It gives me the following error message:

Error with loading: expecting class (CObj), but received ()

I've uploaded a broken file here:

Oh nice but you know there is already a Topic about this kind of bug.

Use search next time.

Ermm I used search for "cobj" and found the exact same thread... but it's not the same error message!

And my Construct didn't freeze when I saved, saving worked just fine. But later files won't open anymore.

So, as you see, it's a different bug.

Almost the same so its pretty much similar bug.

Please, can you post a non-bugged version of the original cap that replicates the bug?

I could post the last working version, but I guess that won't help much.

For me this bug seems to happen if I run Construct a quite long time, change lots of things in my project and keep saving. Sooner or later that'll break my file. When I try to reopen it later on, it'll give me that error message.

So now I'm doing what deadeye mentioned in another thread: I'm working a little bit with Construct, then I'm saving and RESTARTING it. And I restart it often. Haven't encountered the bug since I use to do so.
