AVA Problem

Hello everybody!!
I have been playing AVA for like a week on my new account.. Everything was alright , there were no problems..
But after the last maintenance , when I play AVA , I keep teleporting when walking.. It is very annoying because when I am trying to play like everybody plays , I found out that I can't aim correctly , can't shoot correctly , just because of this teleporting thing.. People even say I am a hacker or something because I am running faster but it is just teleporting in the direction I try to walk..
Well that is the problem I have but there is also a strange thing happening.. I am playing AVA from my home and I have a fast internet connection , I got my ping at about 70-80 , and it still teleports.. But when I play from a friend's home , who has a weaker internet connection and the ping is like over 130-140 , it won't teleport..
What I have tried so far was: Reinstalling the game and Aeria Ignite and Akamai NetSession and everything that was connected to AVA.. I followed a guide on this site about how to get a better connection while playing.. I have tried many registry fixers and also scanned my PC entirely but no virus could by found and every registry error was fixed..
Please.. Tell me what cand I do to fix it? I really need to fix it , since this problem started happening , I am visiting my friend more often haha.. Now seriously.. Tell me if it is a game bug , or anything..

P.S. : Uhmm yea , I have also checked the requirements for the game , and my computer has an Intel Core I7 and a very good video card , it has nothing to do with my PC configurations , but I was just mentioning this , so people won't say that this might be the problem..
