 * We bought the pro version of the plugin, but it seems to habe updated to newer
   version, but we didn’t get any updated files. The PDF are not displaying anymore,
   and when I install the free version from the WP repositary, we got an error message
   that says “PDF.js v1.4.20 (build: b15f335) Message: file origin does not match
   viewer’s”
 * Please help.
