Try copying it from your other Touchpad.
On your Touchpad, with USB mode, or using WIFI File sharing with root accessible, go to :
(for Advance browser)
and copy the folder for the App over to the same location on your other Touchpad.
I've been able to get some Apps from my Pre to my Touchpad (but needed a few adjustments due to the resolution being different between the devices, but since it's Touchpad to Touchpad, is should be a straight copy).
Hope this works for you.
