-1075: XML corrupt or invalid

Error:

Solution:

We suspect that something is going wrong with the XML we send to Nalpeiron at startup, but we don't know for sure. To test this, try using offline activation, but be sure to disable the proxy server settings first.

• To remove the proxy settings without having access to the UI, you will need to modify the INI file directly. The relevant keys are:
  [imatest]
proxy_server_enable = 1
proxy_server_url = http://some.url.com
proxy_server_port = 80
save_credentials = 0

• Setting
  [imatest] 
proxy_server_enable = 0
  should disable Nalpeiron's usage of the proxy server, allowing you to start Imatest and go through offline activation.
