Ah, yes. It looks like the problem is what
trauts mentions above: if you have parentheses in the directory path anywhere, it crashes the decompiler. Odd, since the RPA extractor works just fine with parentheses. I would have thought that either parentheses are a problem or they are not; having them only
sometimes a problem was unexpected. (I also didn't know that parentheses were considered irregular, unusual, or prohibited characters in a directory name. I have been using them for years now to indicate a version number of a game so I know whether I've caught up to current content or not.)
