Hi,
When you import a sound file into Crazytalk 6 this is known as the CTS Length (Script Length). All you need to do is change the Project Length to match the CTS Length as seen in the image below. Just click in the boxes and input the time required to match the CTS.

To make the Emotives and Timeline active you will need to click on the Script in Stage for the character you wish to work with. Once you do this the Emotives and Timeline tabs will become active.
Your third part is a little confusing. I don't know what you mean by Copy & Paste didn't work. Copying and Pasting is a windows function and nothing to do with Crazytalk itself. Maybe you just copied the files to the wrong locations. I would double check this and make sure the folder locations match those of Crazytalk 5.
Alternatively if the Crazytalk 5 content you wish to add is purchased content then I would just install it again but choose to install to Crazytalk 6 this time. This will avoid the problems you having copying it yourself.
Hope this helps. :)
