Can not kill creeps

Hi,

I have had this problem for 30min and can't do anything, so I would like some help from you guys. I have done the first part of the first quest from the 3rd act. Now I have to get into the crematorium and find something / someone but I CAN NOT KILL anything ! not even deal damage to them. When I port to another point of the 3rd act, it's the same, I just can't deal damage, they all seem invulnerable... I guess this must be caused by the fact I need to end the quest, but how could I if I can't kill the mobs ?

thanks in advance

Name of the character : Crios

This is getting extremely frustrating... I can't play at all, I got help from a friend to end the first quest and it changed nothing ! I can cast spells but they don't deal damage...

I paid to contribute to the game and would like to be able to play...

Neok, have u tried relogging completly to see if it fixes the issue?

Yes I did a dozen of time : /

No changes

But I noticed something : My skelettons can deal damage.
