Has anyone tried using Sony Production Assistant 2.0 with Magic Vegas 14.0? I've tried reinstalling but it isn't showing up in the Vegas 14 menus.

I don't use the software but you might find some help here. Good luck.

Edit: You need Production Assistant Pro 2.0 to work with Vegas Pro 14. Not sure but an upgrade price :-(

Sony Production Assistant 2.0 is not compatible with MAGIX Vegas Pro 14.0 as you have seen. MAGIX changing the Script API in version 14.0 which made it incompatible with all previous Sony scripts.

MAGIX is now selling Production Assistant Pro 3.0 which is compatible with Vegas Pro 14.0. You can buy it on their web site here: VEGAS Production Assistant Pro (http://www.vegascreativesoftware.com/us/vegas-production-assistant-pro/)
