Image Upload freeze (.NET)

Hello @ All,

I just tried to upload an Image on my Webserver. I habe a Folder "pic", in my config.ascx i have:

UserFilesPath = "~\\bilder\\" ;
UserFilesAbsolutePath = "C:\\Inetpub\\vhosts\\test\\subdomains\\tsc\\httpdocs\\bilder\\";

The Upload seems to be ok, beacausse the Picture is in den write Folder, but the Upload-Window never comes back. And
I get these Error Message:

Error: Permission deniend
Code: 0
URL: hhtp://www.test.tsc.at/(324234&%$&&"§%"§%§$&)/fckeditor/editor/filemanager/connectors/aspx?Type=Image

Please Help!

thanks a lot
