Administration / Login not possible

[mampfred]

Hello world,

I'm new to this forum and I hope I didn't missed an already existing solution for my problem. When I want to login to my Plesk 11.09 Windows I get the following error message

xmlrpc error: XML parsing failed
---------------------- Debug Info -------------------------------
0: common_func.php3:4684
of_get_all_keys()
1: common_func.php3:4684
pkey_fetch_key_list()
2: KeyInfoForm.php:171
KeyInfoForm->get_bye_online_url(string 'new', string '')
3: KeyInfoForm.php:77
KeyInfoForm->assign()
4: key_info.php:43

There is more information saying that my license key is not valid, but even the update via the command prompt is not working.
Downloading a new key via my strato costumer service is not working either because while trying to install this new key via the command prompt, i get the message that even this key is not valid anymore.. What can I do?

Please help!

Please refer to the steps mentioned below:

1. From the windows server, go to the following path:
"%plesk_dir%\admin\repository"

2. Under the "repository" folder, check the size of "registry.xml".

3. If file is 0KB, delete or rename the file.

Once it has been done, try to access to Parallels Plesk Panel.
