Game keep Crashing every minute after logging in ! , i am trying everything since 1 hour to make to stop the crashing ,, but nothing is working .... first of all  
- checked my Internet connection stability ... but all is fine   ( powered off router and removed my Ethernet cable .. powered off computer and changed my mouse and keyboard slots then i powered on everything 
- cleaned ( Internet history and browser + prefetch files + temp files + used ccleaner + even cleaned computer from dust )
-Turned off my NVIDIA control panel ! + turned off  anti-virus and all protection system in my windows 
-made all game graphic on lowest 
-Repaired game files ! 

and for more Information ,i think i get disconnection as long as i press W to move .. but if i log in and let my character just standing i think i don't get disconnection ! i am still testing this anyway ( i am not sure !!!! )  Also i have noticed something weird  before disconnection ... that i can talk to the people on chat but i cant cast my skills no matter how many i am trying to click then  disconnection from sever pops up .
