Can't login with 1 character

[Lurux]

Heya,

I got this problem with 1 char of me. When I want to log in, using enders, I can only use spawn to hearth fire (not where it logged out).
When I do so, the client freezes and pressing hnh in the taskbar makes my screen go white.
Any idea how to fix this? I tried to replace his hearthfire already. Note : there are moments it does work but mostly not..

Thanks!
