I see that the new Wiki page says it is necessary to add the [ImportOnly] entry to protocols.ini. However, it is already in the version of protocols.ini distributed with RMIR v2.04 build 9 and later.
Since the article was written, RemoteMaster has acquired the ability to import Girr files directy, rendering the article painfully obsolete. I have updated it: Now just open (for some reason, RM avoids saying "import") a Girr file and you are done (at least in most cases).
