Quote the person next time when replying. If you have ccapi 2.70 installed on your pc but trying to use 2.60 PS3Lib.dll your gonna get that error. What I did was install 2.60 on my pc but 2.70 on my ps3 where I can use either 2.60 PS3lib or 2.70 PS3Lib. Just change the PS3Lib to your current version and the tool should build
I'm not understanding, so you want me to unistall 2.7 ccapi from my computer and then re-download it version 2.6?
