File integrity check failed and reported some errors

I tried to open details, but it will not open. I have downloaded and installed these files like 5 or 6 times and still get this error. Is there a fix for this or does it even matter?

When you click on “Details” does it not open a popover?

No.

Ok could you please send me by email matt@piwik.org the URL so I can see this issue myself? Thanks!
