Sorry, but these ideas that Cccam 2.2.1 will work and not Cccam 2.3.2 for example are stupid. Only that you are only a cccam-client .... and the server administrator instructed you to use a specific version of the cccam protocol (usually you can set it up, without changing the softcam).
Every single softcam must work. The differences are only minor. For example, Cccam and Oscam are the same with the difference that Cccam is mainly focused on the issues with the cccam protocol. Oscam is trying to keep all the popular softcam protocols without BUGs. This means that in Cccam there may be a corrected specific missing for just the cccam protocol rather than in Oscam. However, later the bug fix is also applied in Oscam.
Then there is one thing that differentiates softcams - specially developed softcam compilations. For example, if a developer modifies the code for himself, so that, for example, the softcam Cccam will work correctly on a particular case with a particular decoding card problem. Later, the modified code can also be implemented in the main stream of source code development on the Internet - it is only a matter of time (sometimes it takes a week and sometimes even half a year).
My recommendation is Oscam - a multi-protocol softcam. Like Cccam, this Oscam is both server and client in one.
If something is not working then the problem needs to be solved. Find out exactly why it doesn't work. Not that you exchange softcam for some other :-P.
However, it all depends on what encryption is used in your card and it is necessary to identify: CAID, DVB provider, type of card reader (external or internal), Enigma version , ...and so on.
If OSCam or CCCam works, the problem is then in decoding (with paid programs that need to be decoded using the card) or in communicating the card reader with the decoding card. These are the two most common problems.
