When viewing the gamepacks I realized that I had missed a few of the gamepack downloads and decided to download the remain few I had missed. Gamepack 27 and 28 both have the same filename:
gamepack27_v3Arcade.zip
However, the details page for both gamepacks are different.
It was pointing to the wrong file in error.
The download link should be fixed now,
Thanks for the report.
No problem. :)
