Hi Andy,
Ok this is how it went yesterday evening.
Erased the weapondata.dat (actually moved in another safety folder

I found in the Weapon folder the weapons editor.
Since double clicking on it yield no result I opened a CMD from windows/run and then started it.
Worked.
From the tool then I was able to load the weapondata.ini
Not really knowing what to do I simply saved and closed the editor.
I was then pretty suprised to find a new weapondata.dat!
But running again the game left me still without any weapon.
Possibly I did something wrong.

So... yeah, if you have another hint on how to recompile the file that's just perfect.
^_^ Thanks a lot!
