Can't update youtube app?

[Clak]

I'm using blackhole rom at the moment and I've noticed the youtube app included is not the newest one. I can't seem to get the market to update it though. Is there any way to do this or do I need to find an .apk of the newst app?

Nobody knows what I mean here? I just simply need to get the latest version of the youtube app. Can't get the one I have to update, and the other .apk I found won't install, I assume because the other already is.
