Anyone knows where/how to change the IP/Domain inside the unpacked Fire.dll?

Ok, I'm going to continue with this because I really want the client HWID and the basic protection from this DLL.

Maybe others with the same need and more knowledge or wanting to help can join in this crusade 

 

This is what I have/found.

This contain 5 files:

Fire_U.dll - Unpacked. Found in RUS forum.
Fire_P1.dll - Packed. Same file as Fire_U.dll but Packed.
Fire_U1.dll - Unpacked Fire_P1.dll by me.
Fire_P2.dll - Packed. Another version.
Fire_U2.dll - Unpacked Fire_P2.dll by me.

 

If you use Fire_U.dll (rename to Fire.dll in your system) the client show you an error after loading the dll:

 

Runtime error 216 at 1314421A

 

All the unpacked files throw the same error and the error happen here.
