Rtmpdumphelper and cam4 issues

[Rufskin]

A few weeks ago I could record cam4 shows perfectly fine using rtmpdumphelper

now it just comes up with with the error message
ERROR: DECODING ERROR, IGNORING BYTES UNTIL NEXT KNOWN PATTERN!
ERROR: ServeInvoke, error decoding invoke packet

then the rtmpsuck screen will turn gray and say rtmpsuck has stopped working...and then shortly after i will get an error message saying rtmpsuck.exe has stopped working.

Any ideas why its no longer recording cam4 streams?

All and any help is appreciated.

Thanks
