WPE Pro is a quite useful tool thats right, but it only changes things thats client side .. EXP, Money, rates and so on are all Server Sided so changing this just shows to you that its increased, but actually its not, even if u freeze the adresses u get.
Also there are way better Programms than WPE Pro that arent detected by any Anti Hacking Software .. but since the PW Protector is disabled with the XUG client u can use almost ANY programm u want in PW. And WPE Pro is detected as a Virus/Trojan since it is used to be protected by anti hacking systems with a rootkit, and it is a memory editor and seems to be suspicious to AV
