From what this information says, it is likely because you have an old version that needs upgrading. I copied this from the internet for you. There is a lot of information on the Internet if you search with Google.
"Only new Aston cams , with a green Led can be upgraded by satellite .
Last version for the former Astoncrypt cam is V 1.05 , and can't be upgraded .
To upgrade your cam , you will have first to modify the time length of message display in the cam menu to "unlimited" ( Menu / Information / Smart card information / Settings). Then , you only have to switch on your receiver on the right satellite and right frequency , insert your cam in your receiver , and the upgrade will start automatically within 5 ' .
These channels are STB Comag , or Technisat Kanal 50 on the Astra Frequency . Maybe you will need to store it manually .
With Xena 1800 & 2000 , you will have to select Menu / Installation / Download / pcmcia download , and enter the right parameters .
Anyway , you will check the new version has been downloaded , entering in the Common Interface menu."
