Trying to unpack engine, get an error

[Rainscape]

Hey, is there a way I can unpack engine, modify some addresses or strings or whatever, and repack it into an exe? I try to do it via PE Explorer, but it gives me this error:

Error: Can't create New Image File. The original file has been probably packed.

So, can anyone either send me an unpacked engine.exe, or tell me how to unpack it?

I thought people used kernel detective for that.

They use that to dump, idk if you can reuse it properly after that tho

I thought people used kernel detective for that.

He's trying to unpack it further, to its source.

Which won't be that easy by the way.
