again:最新研究结果更新： done!

I used Acrobat pro 9 ext, followed Dao Luan's link, choosed EXTEND FEATURE IN ADOBE READER, save, now you can edit fill and save this fillable PDF file in reader for 500 times.(but nobody's gotta edit one form for so many times.) now you dont need to download 3G reader livecycle extended which cost you $349,and very hard to follow the installation process.

Acrobat pro 8 doesnt work on this feature.

So Dao Luan, what you want from me as return? name it please.
