"unable to validate core data files"

  • Now this is the message I get when I try to start D3. Earlier it would keep saying there's a new patch available even though I already patched it to 2.0.6.

    Viewed the info on this page

    https://us.battle.net/support/en/article/diablo-iii-was-unable-to-validate-core-data-files

    but:

    1) the D3debug.txt is NOT inside the ErrorReporter folder, but in the main D3 folder.
    2) there's no file information in the particular lines, only the below

    2014.06.10 16:17:48.412391100 --- Main memory stats end ---
    2014.06.10 16:17:48.412443400 SNOFileInitializeSigningData initializing.

    2014.06.10 16:17:53.718000400 TerminateProcess via DefaultTerminateCallback with code 128

    and that's where the txt file ends.
  • Diablerie,

    Could you please post the entire D3Debug.txt file?

  • Diablerie,

    Something has gone wrong somewhere with your patching it seems. Basically, it's complaining that your patched game client isn't matching the client version on the server you're connecting to. I wanted to make sure you weren't connecting to another, yet to be patched region, but you're not.

    I'd try running the Scan and repair utility first as it's pretty quick to do so and might help. It's located in the Desktop App under the Options section when you have Diablo III selected along the left side.

    If that doesn't help, I'd have to recommend a complete uninstall of the game and then a re-install.
