Hello Friends,

I have been playing this "AppGameKit Classic - Visual Editor" on Steam for few months. But this type of error I had never faced before. I could not able to verify Steam game files of this game . Does anyone have any idea how can I able to solve the issue? Thank you,

There are a lot of tech savvy folks here, and several that have published to Steam.
I think what they would need to help you is a lot more info than you have provided. For example:

- The source of the error (AGK, Steam)
- What you were doing when the error occurred (ex: compiling, publishing, executing, downloading, etc)
- The exact syntax/wording of the error message, including any error codes, and what your choices were (option buttons, close window, etc)
