Something wrong about this client

My problem is that the game is always crashing my PC, and after that the game runs slow and bugged. To resolve this i need to restart every time this happen which is very uncomfortable. I have played in a Portuguese server and this never happened to me, only on this server/client. I reinstalled the Portuguese server client and that doesn't happened again, then i reinstalled this one and the crashing is still visible, even with the low graphs in-game. My question is if this client or server is using some resource that make this crashing or something else. The problem is not my PC cause i tried different servers and the "crash" only happened here.

PS: Please keep in mind that this doesn't happened in other servers/clients

Thank you

 

You'r might be messed up with other server's files. so try reinstalling everything. and only install Gamez aion.

 

That would not be necessary cause the other file servers were in a briefcase in the Desktop, in other words the other clients were installed in the Desktop and the Gamez Aion is in the Disk
