Someone, somewhere, made a typo in one of the original versions of this line.
disablecrccws_only_for = 0500: 030B00; 0500: 50F000; 09C4: 000000; 098C: 000000; 098D: 000000
The provider ID 50F000 is wrong! It should be 050F00.
Use this in the [global] section of oscam.conf instead
and get everyone else to do the same!
