.txt files showing encryption error

When using domain.com?s2member_file_download=test.txt&s2member_file_inline=yes to display txt file within the browser, it prompts a download.

Then when you open the download it shows an encryption output within my specified file instead of the true contents. This works if I use any other format except for txt. All txt files should be able to be viewed within a browser.

Additionally, when I go to a certain link in my wp-content/plugins/s2member-files folder it goes to a 404 error page instead of redirecting the visitor to the page or page as it does when you try to access content that is not accessible unless your are a member.

Also, any file that you go to within wp-content/plugins/s2member-files/whatever.pdf it shows you the file without prompting you to sign up. I have tested this on another browser/computer where I was not already signed into wordpress as well.

I have ensured that Apache is the latest version as well as made sure that I am using the correct .htaccess file within the security folder.

Any help would be great!

For now I have marked this plugin as being broken.
