Need help to open and convert these files

[Rising Edge]

Hi guys,
Can anyone help me to open and convert these files so I can play them in Windows media player or Real player? They are some sort of .mkg files.

I have a paid subscription to a karaoke website that allows me to download their player to my computer and download AV files through it and play these songs with or without an internet connection.

I would like to convert and save these files to a personal folder where I can open and play with WMP or RP anytime I want to irrespective of if I'm still subscribing or not to the website.

I'm trying to attach a screenshot of the files but I don't see how I can I guess I'll have to describe it. It says in its properties that it is a .mkg file. I guess that's all the info I can see. If anyone can tell me how to insert a screenshot I'd be grateful.

Thanks everyone!
