Build titanium appcelerator blackberry project

i have a blackberry project in titanium appcelerator, to install it on my device i need to build it first, but i cant find any button that lets me build the project. Googling didnt help me at all.

thanks !!!

EDIT: plus i followed the Troubleshooting section in 开发者_JS百科the first link provided by Muhammad Zeeshan

you need to have purchased at minimum a Indie account from appcelerator to have access to preview/beta software.
