Hi WingBro,
This is the answerhub where we offer support for questions about Unreal Engine 4. We do not officially support UDK through the answerhub, so you may not be able to get help here.
I would suggest the UDK forums here: UDK - Epic Games Forums
They will be more likely to be able to help. I would suggest getting UE4 however, as it is only $19 and offers a lot of great new features.
Cheers!
