Not Responding

[luke1005]

When i try to use the v5 installer it says Not Responding (Windows error)
v6 works
but v6 client sucks and is too laggy to play on.
V5 worked for me before
tried to open graal one day got the error.
Tried uninstalling and reinstalling and then the installer started giving me the same error. so i tried v6 and its too laggy to play on. (Fps wise)



What ive tried:
Reinstalling
Virus scan (Completely clean)
Malware scan (Completely clean)
Completely removing all elements of graal on my pc and then reinstalling

None of these have worked, im not reformating as i no longer have my windows disk. What do?
