Game crashes when trying to build pools; BS content vanished

[Gerbera]

I hope anyone can help me with this ...

Recently I discovered that, whenever I click the pool tool, the game just crashes, even on an empty lot. I have tried to set the graphics options to the lowest, but still it crashes. Does anyone have an idea what could be causing this?

The second problem is, that I have just loaded bodyshop, only to find that more than half of my BS custom content has vanished. Hairs, skins, eyes, make-up, clothes, tons of stuff is missing, even some recently downloaded stuff. In some cases it's just several recolors of a mesh, in other cases the whole stuff is gone. I know that all the things were working last time I was in BS and in game. Any idea what has happened?

I have all EPs and SPs.
