You should download the latest official release of OS 6:

Follow the instruction to install the OS on your PC.
Before you connect your BB to the PC, copy CJK.alx to C:\Program Files\Common Files\Research In Motion\Shared\Loader Files\9800E_v6.0.0.141_P6.4.0.64 and the rest of the cod files to C:\Program Files\Common Files\Research In Motion\Shared\Loader Files\9800E_v6.0.0.141_P6.4.0.64\Java.
Go to C:\Program Files\Common Files\Research In Motion\AppLoader, delete the Vendor.xml file.
Connect BB to your PC and double click Loader.exe and follow the onscreen instruction. Remember not to choose Japanese and Korean as I only include the files required to read Chinese.
