FATAL ERROR: Could not unpkg file dev_flash_000.tar.aa.2010_11_27_051337: child process exited abnormally

From what I read it says i do not have the keys installed but I have put them in the extracted folder on my desktop and in ps3keys folder in C:user\mycomputer\ps3keys and Im still getting error. This rar file did not come with an Activetcl app do you still need it for this version of PS3MFW. If anyone has a complete version of this with all files needed please upload or give me some help to solve the problem im having. I ran PS3MFW V1 and had no problems but I need the option to allow update with broken blu ray drive because mine is broken and I need to remarry it and I can not do it running Kmeaw 3.55
