With reference to this question and this other one.
Here I’m having the same issue with brand new installation of Unity3d 4.6 on brand new windows 7 ULTIMATE x64. I’m running it under VirtualBox with good memory configuration and 3d accelerator enabled.
The problem is that when I click to open the asset store it loads a white window with just the above part displayed correctly. After a few seconds it freezes and it appears a dialog saying that the editor has stopped working and will be closed.
This happens 100% of the times.
Trying to import packages directly from the editor I get the error saying
Error building package The server was
unable to build the package. Please
re-import.
So, at the moment I cannot deal with assets or tutorials via the asset store. The only thing I can do to achieve this is to have a friend downloading assets, creating projects and passing it to me, but this solution is not acceptable.
Any clue to solve this problem?
