DLLs unavailable for download

[speige]

my site uses a few dll files for a silverlight application that need to be able to be downloaded onto the machine browsing the internet (obviously they're never executed on the server). When I uploaded the site several weeks ago everything worked fine, however recently (about a week ago) I get an server error page, however all of my other pages download fine.... Has there been a change in the configurations disabling dll files ?
Edit:
I mean, when i specifically type in the url for the dll, the dll exists and everything but the server denies allowing the browser to download it. I can navigate to the directory listing above the dll from the browser and it shows the files are there.

Can you post a specific URL in question? One that is supposed to be downloading?

How about an .htacces entry to allow the download?

Try adding this to your .htaccess file:

<FilesMatch ".dll">
    Order allow,deny
    Allow from all
</FilesMatch>

Edit:
I changed the .htaccess under my public_html of my main page like you said, and uploaded a dll into that folder and i get the same issue as before. http://www.intelligentspanish.com/Language.dll

There are settings in the default mime types to accept dlls, so I don't think this is the issue.

The error I get is:
503 Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

The weird thing is that that DLLs were working 100% fine two weeks ago..

Sorry about not being more descriptive before, I always hate it when people don't give any detail... I must have been asleep when I submitted the post.
