url not valid

[ullone]

I have installed your script here :
http://www.eulisse.com/myred/
Yesterday i have register a subdomain for test it and all was well.
http://www.cancellatemi.eulisse.com
But today when i try to test some link to register i obtain the same error : url not valid.
I have test this links in your demo site and in other site that use myred and all accept this domain. All in my site it give me the error "url not found". I have also tried to register the same link that i have regitered yesterday and also it give me the error "url not found".
I do not understand. ...

I have not make any changing in my configuration. I do not think that some changing are made by my provider. ... ...
