Error message after x64 installment

I cant post image so …

I get a error message when trying to create a wall lantern,the lantern is built but no model of it and that seams to be
the main problem of the bug. Created beds, windows and doors without any problems.

Win7 ultimate
8 gb ram
i7 processor
intel 4600 hd graphics + nvidia gtx 760M (all with latests drivers)
