I've visited now ExeShield homepage and downloaded their latest version. It's 2.8b - in this version they have removed Xtreme Protector envelope!.
I can only suppose they have tried XProtector (there is option like this on XProtector page) but after reading ExeTools forum they changed their mind...

I'm still trying uploading the version described in this tutorial to FTP (I've problems with password - dunno why....)
