New Oscam versions not working with MuMudvb

Hello has any one come across this issue.
Old Oscam versions / Phoenix card reader / MuMudvb / TBS / = Working.
New Oscam versions / Phoenix card reader / MuMudvb / TBS / = Not working.
With the new Oscam versions it shows as the ecm as found but with MuMudvb it does not decrypt just black screen.
If any one knows the issue please let me know.
Thank you for your time.
