WP Minify and MaxCDN

Hi guys – i’m trying to use WP Minify to combine and minify my CSS files. This works fine, until I turn on MaxCDN (via SuperCache). The file is created on my server (I can locate the file), but when it is supposed to be pushed to the MaxCDN zone it fails for some reason, resulting in my website loading without CSS.

Any reason why this is happening? And is it possible to exclude the WP Minify .css file from the CDN? I tried adding

I tried to enter the path to the Minify directory in ‘Exclude if substring’: wp-minify

And tried to force it to include it by adding this path in Include directories:
wp-includes,wp-content/plugins/wp-minify/cache

But neither seems to work…
