unpack data.pak failed ?

i have founded a pserver , it is good , i want to unpack data.pak by unpacker , but failed , nothing show , how can i unpack it ? why can't i unpack that data.pak ? help will be appreciate .

There is so many ways to protect data.pak from a unpacker its not worth the time to list. To put it short and sweat, the servers data.pak your trying to unpack is protected. This could range from custom entry points to custom encryption. So if its not working, then you will have to unpack it manually.

i saw it has +10 failed back to +9 , this is what i want to know from data.pak .
