Hello,

I have installed GNU Radio Companion 3.7.13, under module selection RMG Encoder, RMG decoder blocks are missing so that i am not able to do tutorial mentioned at [TutorialsSimulations - GNU Radio](https://wiki.gnuradio.org/index.php/TutorialsSimulations) this site. What to do in this case? Please suggest.
