Lost MainConcept 1.04 Serial

Hmmm, I just tried skipping the serial number and it let me install the
"demo" version. That made me recall that there was a link embedded in
the Adobe Encoder to activate this codec, that's gone now. I don't know what
this program is that I downloaded, it looks like a newer plug-in program.

Does anyone know if I can retrieve the free MPEG encoder that originally came
with P. Pro 7.0?

Thanks
