Client Problem...

[karuls2]

Hello I have a pretty annoying problem about game client.Whenever I open the launcher and press start game the client opens but after the acc and pass details pressing confirm just freezes it and stops giving response so I need to close the tab.I have seen same kind of issue of Rage of Sage Online and there deleting music file in pko folder solved the problem.I tried the same for here but it's not helping.I can only launch a succesful client maybe after 10-15trys and it makes 15mins.My computer has i5 3337u ,intel hd graphics 4000 and 6gb ram,a toshiba netbook.I believe it's not a problem with my computer.If I cant solve this I'm planning to quit the game unfortunately...
