Matinee example not letting me copy files over to other projects

Like the title says, when I try to copy files over from the content folder in the matinee example to another project, i just get a grey box whenever i drag and drop a mesh or particle into my scene?

Both projects are 4.9

Are you using the merge tool or just directly copy and pasting?

D-Directly copy and pasting o-o…is that a bad thing?

I know not of this merge tool, I am a noob at udk

Right click on the content folder of the project in editor. Merge from the currently open project to the new one.

Thanks very much this solved my issue entirely!
