I have placed a DRMX or DRMZ file on my web server but the link to it does not work

The problem is caused by your web server host not recognizing the file extensions. There are three options for resolving this issue: (i) ask your web server administrator to enable these extensions – Linux/Unix servers are generally OK (but are case sensitive so make sure you have specified the URL correctly with the case as per the filename) but Windows servers require a MIME type declaration of application/octet stream ; (ii) place the files on a separate file server that does not have these restrictions; or (iii) place the file(s) in a zip folder and link to this zip file rather than the DRMZ or DRMX file(s). It is often a good idea in emailed instructions to end users to include zip file downloads as an option – zip files work particularly well for Mac OSX users.
