Getting Computace to respond to removal?

This machine was acquired used and I am having the hardest time with Absolute Persistence. I already called Absolute and they cleared it out. However this generation of Persistence is a proper pain. I put a fresh copy of Windows on it and then wiped it today intentionally disabling ALL of the firewalls and keeping it on public to prevent network hazards. I also put it on an Asus router and it is not responding in the times older Persistence 1.0 machines do :-(. I even tried HP BCU to force it off, it did not take the /set: command or directly - it is nasty on these. What can I do to force it to check in, even via CLI?

If anyone is seeing this and thinks you shouldn't buy a Persistence affected PC, don't let it put you off - 1.0/2.0 are easy, the PKI versions are a bit picky - I knew this when I got it and Absolute cleared it. You just can't use it for a few days due to the security issues you need to create -- but KNOW what you are doing.
