Package File Invalid

view story

http://forums.androidcentral.com – I have a Sony Ericsson Xperia Arc and I recently bought Clouds & Sheep premium for $1.06 but I can't download it. It shows package file invalid, so I wiped google play data and cache, frameworks too and rebooted phone. It did nothing but mess up my google play store connection, I then had to delete my account and reboot again and log in. I still get package file invalid. I honestly have tried almost everything, nothing has worked. How do I download this game?! Phone is NOT rooted, currently got 4.0.4 version of Android and i had this issue once before I upgraded to 4.0.4 and the fix was (HowTos)
