Question about FileArchiver r3869 / r2806

[Suainzettello 29]

Hello everyone,

I downloaded the files mentioned above, but I made a change to the keys and LZO XTEA to give that a little protection to the client.
It works regularly, in fact I packed the new files with the new extensions "exs" and "ext", type = "2" and new lzo and xtea key.
The problem comes when I go to unpack new archives, it is not working.
It should only pack unfortunately.
How is it possible? I checked and rechecked by HxD and nancy, when I go to unpack still marks me extensions "eix" and "epk".

 

Help me.
