Hi I"m a new member here. Just want to ask for help. I tried side-loading apps and games in my playbook (os 188.8.131.528). Though I have installed some apps and games, it seems that it choose only what it installs. Most of the HD games or high-quality games cannot be installed, and it prompts "package cannot be determined". I think it has to do whether the .bar file is a zip file or something. Need your help guys here... Thank you very much!
