Thanks, Kil,
patchme fixed the problem
![Very Happy :D](./images/smilies/icon_biggrin.gif)
so I could log on successfully and raid. I had bad luck tho, the day after, my internet connection disappeared completely, and I had to buy a new router... Now I'm crossing my fingers and hope nothing else goes wrong
And the first problem is gone, too, I don't have to bypass the patcher anymore, and lagging less (but still a bit more than usual).
Thanks everyone for your help.
