Fatal error! default resources

Hi,
When I launch unity to open a project that was working perfectly it crushes displaying the following message:

Fatal error!
Couldn’t copy default resources!
You might be out of disk space or your project folder has no write access permissions.
You can open another project folder by holding down alt at startup.

The problem seems to be related to the folder of that project, because Unity works if I create a new project to work with.

I changed the permissions of my project folder to 777, but it still doesnt work.

I tried deleting myprojectfolder/Library/unity default resources, the first time I did it, Unity succeed to open my project and I was able to work with it for a while, but next time I launched Unity It didn’t work, I tried deleting that file again but that doesnt work anymore.

Anyone have a clue of why this all is happening?

P.S: Im working on a network account, maybe that is related…

Thanks a lot,

Tomas

What does OS X’s Get Info window report for the folder? Do you have both read and write as expected?

And can you “Apply to enclosed items” successfully?

It does sound to me like the server could be the cause.

You probably want to use your local drive with Unity 1.6.2.
We have done several bug fixes to make Unity work over Network drives in 2.0.

Thanks for your quick reply,

Yes, the permissions are set to both read write,
and yes apply to enclosed items works, I tried it several times, but I doesnt solve the problem.

Thanks a lot for your help again
