After trying this method that worked fine by the way I discovered another method more easy and I think it will work on future realeases. It´s easy because you just have to edit one file after download the game from the market and then download yourself the tables. I will explain it now the easy way possible:
1. Get the app SQLite (If I need you to say how to find the app you wont make It after this)
2. Install the latest version of Pinball Arcade from the Market.
3. Open it at least one time to create the db.
4. Close the game and open SQlite (wait for all the db's to load) and find Pinball Arcade DB's there.
5. After entering the db's open "pinballArcade.db"
6. Open then "purchased"
7. Now you have to press new Record and insert this new 4 records (one after another). On the first line you put the text on the second line you put "1". It will look like this after all the lines are created.
four_pack 1
pack_two 1
pack_three 1
april_pack 1
After this you can open the game and download all tables one by one has you purchased them. And you can leave internet on and login as guest also. Sometimes the games shuts down wile downloading or after but if you open again it will download again and work fine. This only happened to me during some tables download but not a big problem.
Hope this works for you and leave soem feedback.We just have to wait for new tables and find the pack names to add the DB
