Error installing Ace

Running Rev on MAMP on Macbook.

Been trying to install Ace. Keep getting this error...

Console running...

Attempting to install package with signature: ace-1.6.5-pl
Package found...now preparing to install.
xPDOZip: Error opening archive at /Users/eagles9999/Sites/RevoSandbox/core/packages/ace-1.6.5-pl.transport.zip
PHP warning: ZipArchive::extractTo(): Invalid or uninitialized Zip object
PHP warning: ZipArchive::close(): Invalid or uninitialized Zip object
Could not unpack package /Users/eagles9999/Sites/RevoSandbox/core/packages/ace-1.6.5-pl.transport.zip to /Users/eagles9999/Sites/RevoSandbox/core/packages/. SIG: ace-1.6.5-pl
Could not install package with signature: ace-1.6.5-pl

I have tried unzipping the package independently also and get a corrupted error.

WayFinder installed without a hitch.

Any ideas would be appreciated please.

FIXED.

Downloading and trying to install some packages are fine, like getResources, getPage, breadcrumbs install. No problem.

Others such as TinyMCE, Quip, Articles and Ace all fail with the same error as above.
Test the zip file they all seem corrupt.

So, downloading directly from https://modx.com/extras/​ then the package is fine and installs ok.

Go Figure! :-/

FYI, after doing that, you can set the provider for each package to the MODX repo so you'll be notified of upgrades to the package.
