EliteBook 8560w encrypted disk – boot error “MCafee Fatal Error 0xEE020006”.

Hello everybody,
p/n XX058AV, My notebook. Hard disk was encrypted by HP Protect Tools (Drive Encryption, powered by McAfee). Few days ago my notebook stopped while booting with the message in a black screen given here.
"mcafee endpoint encryption Fatal Error 0xEE020006 Getting Disk info"
What can I do to boot or to decrypt Hard Disk? I backed up the encrypting keys.
McAfee gives disk decryption by boot CD (McAfee EETech), but it needs "Code of day" and I haven't got such a code. McAfee told me this code is given by HP.
Please give me your help to solve this error.
Thank you.
