did you recently change your app’s name in the config.json? I guess it’s not an 1.4 specific problem, but a problem with the app name, as our internal logs suggest:
res/values/strings.xml:3: error: Apostrophe not preceded by \ (in Impossibru's Blockoban)
We’ll fix this with our next Build Server release iteration the next couple of days, in the meantime you could simply remove the apostrophe. Thanks for the hint!
Regarding your BB build, it seems that you were trying to make a “test build”, meaning that you must provide your own debug token in the zip package like described here http://v-play.net/doc/vplay-deployment.html#building-your-game under “BlackBerry debug token”.
