After my 31 days of trial ended I tried to change some .reg files,
And I found out how to get another 31 days of trial all over again

,
without need to download the update on the official site.
Follow those steps:
1) Close all of your Sai programs running...
2) Open the SAIMINATOR.reg and press OK
3) After you done open your Sai program, It will say it is the first run, just press OK.
I don't know if it will work for you guys but try it and post your comment!EDIT: I had attached the .reg file for your comfort - follow the steps noted above! (Steps:1-2-3) --You must login in order to download it--________________________________________________________________________________________________
Finally the SAI-MINATOR is out !!! Finally

This .reg file will be sure to make your expired Sai into a living 31 day trial Sai !

Just open the Zip and double click SAIMINATOR and press OK
(Be sure to change your sai folder location ,ex: C:\programfiles\Sai >> C:\WHATEVERYOUWANT\Sai)
Be sure to read the README in the SAIMINATOR.zipIn any contract, Always read the small words ! - Download the latest version of Sai and don't delete it ! It can be that the programmers will find this trick and modify Sai to withstand this trick ! -________________________________________________________________________________________________
