Flip for Mac and Easy WMA

So, I am having a lot of trouble trying to get some WMA files to play on my computer. I downloaded the Easy WMA, and it will convert the songs, but then when I go to play them, it shows on itunes that they are 0:00 minutes long.

And with flip for mac, I try to go to use it with quicktime, but it just says something to the extent that it doesn't support that type of file.

Anyways, any help would be amazing!
