Plant 3D 2012-objects are missing and ortho update error

[Anonymous]

Hi,

I have mayor problem with Plant 3D 2012 version. First i had problem that it didnt managed to update orthographical views. Error message was that there are invalid solids, so  changed all solid objects to Plant equipment. All was working fine still today morning. I opened my project and great news, All pipe bends and fasteners where gone, i can see that pipe segments are connected, but bends are invisible. Oh and ortho update dosent work again, now there are two error messages Modeling error and invalid solids.
I´m out of ideas, please help.
I have tried audit and reinstall, no succsess.
