audio file unsupported filetype

hello, I'm looking for some help with an issue I'm having. At present I have Four Sermons on my website. Three of those have a .mp3 audio file attached to them and the audio is both works and is downloadable. But the Fourth sermons audio which is also .mp3 but when I go to the page on my site for that sermon where the audio file is listed normally it says unsupported filetype. I have checked all my settings between one sermon and another and they all seem to be set right???
i am currently using version 4.5 with joomla 2.5.14

Can you give me an URL of your site so I may have a look?

Yes

www.lovingod.org/knowing-god-and-hearing...e-of-godly-character

Can you make sure you don't have entered a space behind the filename? Looks like this may be the issue.

Thank you very much. Your solution was the correct answer to my problem... Hard to believe I missed that or that such a simple thing can cause such an issues.. Thank you again for you help and thank you re-instating my account. Next time ill be sure to use the proper tools for things like links and what not.

I'm glad it was an easy one
