Youtube Copyright Help Please!

I made a let’s play on Game Dev Tycoon here. But Youtube says it’s under copyright. Can someone help please? There is a box I can write in but I am not sure what I should say.

As stated in Game Dev Tycoon’s EULA you are free to upload and monetize your YouTube Lets Play. However, the background music is an exception: this you can not use, as the music company licensed Greenheart Games to use it in GDT, but they haven’t licensed YouTubers to use it in their videos (however I believe this is not the case as the background music is license-free, but oh well)

Anyhow, I suggest you watch this video (even if your video was not claimed by AdRev): http://www.youtube.com/watch?v=hMTTvPB94_Q

Just Dispute it

thanks!
