Asset Store submit error

Hi all,
Im trying to submit an important update to my package on the Asset Store (UnityCar), but im experiencing errors inside Unity.
I tried several times without success (AssetStore null pointer errors and 100% CPU). Last time i tried I obtained the screen you can see in this image:

why im receiving these errors? Does the submit completed successfully or not?
How can I avoid these annoying errors?

Im using
Unity 3.4.1f5
Asset Store Tools 2.8

my package of course has been validated.

Thanks,
Michele

any help apprecieted here, im waiting for an official reply from Unity, im loosing days of selling here

ok i figured out with the help of a friend of mine (deth_moroz). You have to change target platform to desktop. If you have your target platform to Web Player, for some unknown reason Asset Store Tools makes a mess with crossdomain.xml.
Hope Unity fix this bug soon.
