 Protection using Ring 0 are very unstable, I tried Themida (ex
XtremeProtector) on many computers with different OS (Win95, WinMe, Win2k,
XP, 2003 Server), CPU (Intel, AMD, Cyrix)... I got many random reboots or
crash, it's was a same problem with XProtector.

Sometimes work... I don't know why sometime I got a reboot of system
...without changing nothing... just execute :-(
When you have this bug report from the customer, can imagine time lost to
know where the problem come and to fix it ...

Currently Themida is same than XProtector... for me is unstable ...
