For some reason I cannot compile Multimarkdown -> RTF since I upgraded to the latest version. Oddly, when I was running the beta version, the compiler worked fine!
Now the MMD->RTF outputs HTML code. Attached is a sample of what happens.
It is possible that I have another MMD installed somewhere, but as I said in my post, this error was not happening when I was using the beta version of the current Scrivener release.
