From theire FAQ (already Point #2):
I secured a .exe file, but it won't launch.
When an .exe-file tries to read from itself, like a self-extracting .exe or setup.exe it will fail. Our wrapper encrypts it, so that the .exe can no longer read from itself, and fails to function.
You could e-mail us the file so we could look at it.
So, as you try to wrap a wrapped app, the wrapped wrapper got disrupted.
I would suggest to do as stated in the FAQ and send them the file that they can look into it.
