Hi,
CWS_KEEPALIVE = 300 is for newcamd.list of Mgcamd emulator.
If you adjusted Cccam by yourself, you need to consult the billing, My subscription sub-section. Under the table with your subscription, you will see variuos settings for different emulators. Find Settings for Cccam, click SHOW/HIDE and copy-paste what you see to the Cccam settings. Then, restart emulator.
Check also if only one emulator is activated in your receiver. Maybe, together with Cccam, some other emulator is active too. In this case, you need to delete it or disable.
