There is NO problem with Polish packages (Polsat, NC+).
Use recommended emulator (Mgcamd 1.35), cause stable sharing is guaranteed only when you 're using MgCamd 1.35(a) only.
Delete unnecessary filters from Oscam (if any).
In NC+ package, previously we used Conax encryption, now we are using Seca encryption.
Enter the billing system and check, compare the CWS lines provided there with those available in your newcamd.list configs. Delete unnecessary ports (if any), filters (in case of Oscam emulator) and restart emulator.
One more advice- change server via billing and re-instamm emulator. Everything must work.
