I can't import the furnitures in my project

[Moleu]

Hello people.

I'm having a big problem because I can't import new furnitures im my project.
when I will finish the importation, appears a message:

"Can't save preferences in file system"

Is impossible to install new furnitures and new textures.
I made everything possible to fix this problems, I installed the newest version of Java, I updated the Flash Player, the video card drivers are ok.

Please guys, help me......

This error can happen if you don't have write access to applications data folders. But if this is the case, other applications shouldn't work correctly too...
On what system do you use Sweet Home 3D?

I'm using Windows Xp Professional SP3 (build 2600), videocard: GeForce 8400GS, Sweethome 3.2 version.
About other applications I haven't similar problems.
Previously I've used this program without issues.
I formatted my pc with the same Windows that I used previously, after installing Windows I can't use normally Sweethome.

But, what I could do to enable write acess?
Thanks for helping......
