There's a specific forum for Adobe CQ Cloud. Did you try to ask there?
I did try there, and got an answer which allowed me to upload packages to the cloud.
Well, the chance to someone answer it here is smaller, I think. Anyway, let's hope that someone can help you.
I didn't, what i'm saying is that this is the CQ5 forum, not the cloud one. I, for example, never have used the CQ Cloud, only the "on premise" CQ5.
