Import the aia Projects from your MIT App Inventor to a USB stick using a friends computer. Since your laptop broke, how are you going to access a third party downloadable 'version' of App Inventor? MIT does not support the offline versions made by third parties. If you have figured out how to use a downloadable app inventor clone without a computer; congratulations. Didn't know that was possible.
If you have the offline 'version' loaded on something, simply upload the aia's on the stick to the computer you use for the third party offline clone.
