You're welcome! I'm glad we were able to help. Very often a problem in the binary data is not recoverable.
Note you can post in Chinese, the forum has a button that translates it into English for me, so it's easy to communicate in different languages. For you, there should be a button to translate my English posts into Chinese:

Unfortunately it's difficult to find the position in the file that has the problem. To solve it yourself, you would need to try to load the data using a 3.6 runtime and write code that keeps track of how many bytes were read before the error. Then you need to edit the file with a hex editor and change the bad bytes.
That's probably too hard for most people. Here, we created a new 3.6.53 Skeleton Viewer that reports the byte offset when reading a binary file:
http://esotericsoftware.com/files/skeletonViewer-3.6.53.jar
When you load your original project with it, you'll see an error like this:

That's the byte offset you need: 270197. Open the .skel file in a hex editor. I like XVI32 (here is the download link). Click Address > Goto and type 270197:

The cursor jumps to that address:

Don't worry that the binary data doesn't make sense. The problem is just before the cursor: FF FF FF FF 0F are the bytes that mean -1. We need to replace them with 00. Select the first FF and press delete 4 times, then type 00 to replace the 0F. Now it looks like:

Save the file, and it's fixed!
