Bro, i had the same problem with u when i first used win7.
U need to keep restarting PPS tv if it stucks at 66%. I restarted more than 10 times to get the list of dramas.
Don't worry, u just need to close PPS and then restart the program to let the list download.
That's my way that solved it.

I assume u install the language pack already but still cant see right.

Go to control panel>region and language>administrative

under non-unicode programs, select chinese.
then your pps should be showing all in chinese characters.
