Thanx for the tip!
The problem seems to be the user rights.
The Folder has write protection and Im as Windows 7 user have no permission to change that.
I could cry, but everytime I change the permissions (including subfolders and so on) its protected again when I check the permissions afterwards.
So, he doesnt seem to accept or remember it.
I tried to log into windows 7 as admin, but I couldnt do it.
Is there any oher possibility? Icant find a way to change the rights as admin...
Thanx a lot!
