Have you tried turning off at the mains and then back on whilst the CAM is in, Cowboy? There do seem to be issues with the matrix reloaded on first initialisation after flashing, it can be initialised using the PMCIA slot of a laptop with the correct drivers.
Thanks for your help RolfW, you might have seen this post in a few forums, sorry about that but I wanted to get up and running quickly and I didn't know if I'd get any replies.
So on to the cam..... I've done all things, power off with cam in, out etc, etc. Since my last post I have been round to a friend who has a Force receiver and the cam initialises and you can then enter the cam menu and it lists all the encryption system and software as being 1.055. I wasn't able to test it on a channel because he was just looking at astra 23 degrees, but everything seemed fine, at least it was showing a cam menu which is further than I have got with my Humax. I had heard that if you initialised the cam in another receiver it would then work in the Humax, but after initialising it in the Force receiver it still came up with the message 'Invalid CI module' in my Humax. Any other suggestions would be very welcome....you say there are drivers available to use in a laptop, what are they called and what sites might I pick them up from?
Thanks again, you've helped me in the past and I'm very grateful for your help again.
