Some users may find it.
Yes, today is 3/20. And muxer function in PEnGUIn(Encoder) was expired again.
I am still waiting for the newer beta or commercial version of Perl Dev Kit.
Before ActiveState release it, wish users can adjust date before 3/20 temporarily.
I will update the PEnGUIn(Encoder) when PDK is released.
Very very sorry about it.
