Call the Openzone helpdesk - the number is normally on the logon page.
The other thought and something deep down seems to be reminding me although I don't know what, is connected with your password. In the distant past I remember either having a problem or sorting out a problem with WiFi logon where the password contained a couple of non-alphanumeric characters and for some reason, something somewhere did not like them and the login failed. Tweaking te password sorted it. Don't ask for any more details - I cannot remember, except that it happened and could not be explained.
