I have Vegas pro 14 64, with PA 3.0, I have made a large template with named slugs, so when I use the Template mapper to assign the slugs files (from different locations) I am able to assign all the file I wish. ONCE I PRESS OK, nothing on screen happens, only the folder and .veg file is made, and the PA 3.0 remains open. I then opened the created file, and it is the template only no media files loaded. IF I ADD FILE TO THE FILE LIST, then press OK Vegas opens, and the file are loaded into the slugs. (BUT they are loaded in the sequence as loaded in to the list, not according to the Template mapper as I need them.)

So, the Template Mapper is not adding media files to the project only creating the .veg file name in the fold name I have assigned. I could use the file list to move my files in correct order, but isn't that what the Template Mapper is for? PAGE 8/9 of instructions

[OK: Clicking the OK button will create a new project from the template selected and
start Vegas Pro. It will copy any media to the destination, then build any media bins
from the project file folders if you have requested this, and it will replace any media
slugs in the template with the media that was specified in the list.
