Last status about CrossFire Mod was already explained in my message here:
viewtopic.php?p=1967#p1967(and Alex, you did even post in this subject)
I will repeat here:
CrossFire Mod authors have added security systems to their mod so tools like Freelancer Companion won't be able to function and will crash.
Moreover, they have expressed the desire not to be able to use Freelancer Companion with their mod.
The task to overcome these security measures is too difficulty for me, so I won't be working on it.
The only strange thing is that now you're saying that it makes Freelancer Companion crash "silently" whereas before it used to crash with a Windows message (see tzoy post). Maybe this is due to a difference of configuration in your Windows OS error reports.
