To allow players to further play PSP, Sony develvop Media Go software to make users further play PSP. Players can more easily transfer a variety of media information between computer and PSP.

However, the latest updated version this software has emerged a number of problems.You will be reminded to upgrade to version 1.2 when you open the PS Store by Media Go. But it still shows that version 1.1 after you have downloaded file and installed the upgrade, and still can not open the PS online store. There is an Internet user said he has upgraded to version 1.2, and the installation program shows also a version 1.2, but he got a installing impediment to a successful when he installing the program.

It seems like that offical suddenly discovered problems after it has released the version 1.2 intallation file, so the emporary installation files will be replaced with version 1.1. But the PS online store did not cancel the validation and still require to upgrade to 1.2.

It is no doubt that Sony must spend time on resolving this problem while the time is difficult to determine. And we still have not seen any offical instructions.I am afraid we can only wait for some time.
