Hello, I downloaded and extracted the Mega client. Now I want to start Diablo, but I keep getting this error. How can I fix this? I've attached a screenshot of the error.

Hello, thanks for reporting the issue.

We are currently in the development phase and finishing important changes to the servers. During this process, errors like the one you mentioned (.build.info file or Data folder not found) can occur, as the client is not yet ready to be used.

👉 We will officially announce when the client is fully ready and available, along with the final installation instructions.

Also, I’ve merged the two threads you created to keep the forum organized. Please try to use a single thread per issue going forward.

Thank you for your patience and for following the project.
We’ll keep you updated.
