fileDownload max file size

Hello Everyone,
I have the fileDownload plugin installed on my website and love it! Although I have recently had a content user upload files into a folder that fileDownload calls and there were a couple files that would not download when the link was clicked on. When clicked on we would get a browser page that said "This webpage is not available" or when attempted to be accessed via tablets it would say "the connection was lost". I noticed that of all of the files that have been uploaded the two that didn't work were the two largest files. One was 10 MB and the other was 25MB. Does fileDownload have a maximum file size that is inhibiting downloading large files?

Thanks in advanced for any help!

There's probably not a defined limit, but it's possible that the server simply runs out of memory because fileDownload loads the file into memory before returning it.
