ok thx for this tip, it worked and I completed the tutorial now as I entered the real thing the game crashes after 3 minutes and still can't target with the mouse

I just downloaded the game a couple of days ago just before the server crash. Today I tried it and it worked, I have set up my character and entered the world and tried to communicate with an NPC. First it was targeted and I said "Hi" and it replied, then the problem happened. What ever I say to it "give me a quest", "tutorial", "give me a tutorial" it responds that it didn't understand what I was saying and tells me to not get frustrated and try to simplify the question. Moreover targeting stopped to function as I couldn't target anything else, even the first NPC that I've targeted, with and without "/target". I restarted the game and the same thing happened, it seems like I can only target once and speak one phrase. I have tried uninstalling and re installing but its the same issue all over again, tried updating but the updater says that it doesn't need any updates.

Can you please tell me how to fix this. If there is any fix. I am using Linux Ubuntu 8.04 (fully up to date) and I don't have any other problems or at least I think so as I haven't been able to play much of the game yet.
