no way to delete a corrupted site

[tbegin]

Hello I evaluate Alfresco and want to test it in my company intranet,

I get trouble to remove a site that was created by copying  the sample site provided with the Community installation of Alfresco 4.0d.
I can't remove it, neither with Explorer nor with Share (tried in Repository or Document Space). I took site's ownership with admin user but it didnt help.

in Explorer I have:
"Unable to delete Space due to system error: 08203299 st:site deletion is not allowed"
In share i failed to add admin as site user.

In log i have:
UnknownAuthorityException: 08203303 An authority was not found for GROUP_site_Copie de swsdp_SiteConsumer

I got the same problem while importing a site that was previously exported from another instance of Alfresco 4.0.
How can i use the import/export function corrrectly?
no way to use the imported site! the admin user cant access to it.

You can't delete sites through the "back door" such as through explorer, only through the site service.

Once you "took ownership" as admin you should have been able to delete the site through Alfresco Share.

More details please,  why do you think this is a "corrupted" site?  And what do you mean by "took ownership"?

I mean by corrupted site that no user can access to it.
The matter is that despite my admin is owner of the site, I have an error: deletion not alowed in Share site UI.

Did you see my log?
it seems that site groups do not exist; but why and how to do without these system groups?
