Have you tried your Cam in both CI slots? If yes and your receiver still isn't reading it then it could be a fault with your Cam, your receiver or the patch.
If possible try your Cam in a different receiver, if you have one, or a friends receiver, or try a local satellite shop and see if they will test it for you.
If you have another cam try that in your receiver to see if it is recognised, if you have a multicam, like the Dragon, Diablo, or even an old Magic or Matrix cam, try these as it could read your card, as they emulate Conax cams.
You could also try doing a factory reset of your Technomate, by downloading the official software, from the Technomate web site, this will mean you will lose all your channels and settings, but these can always be added again.
Some Technomate receivers allow for a card reader to be fitted, which might be a good idea, have a look into this possibility.
As a last resort you might have to buy a new cam, but try other possibilities first.
Please keep us updated with your progress and good luck.
