You scared me with the heart attack comment! I moved your post to our Endpoint Encryption area so that an expert will see it.
There is more to data recovery then just information posted on that URL.
And for your other questions the answer is no. SafeTech utility is available from Endpoint Encryption Manager application, that your IT people have access to. Daily codes McAfee distributes to authorized personel only. I guess you are not authorized.
So you must convince your IT guys to perform above for you. Then you need someones experience in removing encryption and recovering data.
