For the issue raised by mmbussacarini and dev_apocalypseboy, I hope this might help. From your description of the problem, you may have the same issue I did. After getting the “Fatal error: Class ‘downloadable_file’ not found in /wp-content/plugins/email-before-download/email-before-download.php…” error, I discovered that I had installed the “Download MANAGER” plug-in, and not the “Download MONITOR” plug-in, which is where the downloadable_file class is defined. After I installed the correct plug-in, everything worked.

In my case this turned out to be an interaction between this plugin and the SEO Ultimate plugin. Leaving the Title and Description fields blank in the SEO Ultimate form caused the error; filling in those two fields corrected it.
