iLok Pace protected app terminates...

[Black_Legion]

I'm working on unpacking/patching a software which is protected by PACE InterLok v5.9.5.3483.
I tried some anti-anti-debug techniques used in Olly plugins to finally open/debug the program with Olly. but when the Authorize dialog (of software) comes up, the process terminates after 3-4 seconds..!
i also used timing anti-anti-debug techniques available in ScyllaHide plugin, but not useful.
anyone knows how can i bypass this process termination?

(as i know iLok has a driver "Tpkd.sys" which prevents from debugging, but i don't know how to bypass it. i already read some documents about iLok, but they seems to be old. this tpkd version is about 5.9)
