I downloaded the SVN today (312kb) and now I don't get the the error message when trying to configure. However now the range logorule for 16:9 is not working anymore. I tried to put the older build back (316kb) and then the 16:9 rule is working but the config gives me the error message.
lol, I didn't even touch the logo engine in a while. They only thing I can think of is if your logo image was in the banners subdiretory it might have been moved automatically when the new build tried to migrate all your banners to the new directory. If that is the case the log would tell you that it can't find the logofile (does not exist ... .skipping) and you can fix it by pointing the logo rule to the new location or moving your image back.
It depends on when your videoaspect ratios were first imported. At the beginning it was not read out in a numerical way, but some string representation of it. I have later changed this, so newley imported episodes should only have numerical values.
To get your "old" episodes up to date, go to config and click force update of mediainfo, in the popup say no. Then it should work.
Tried forceupdate with both pressing yes and no to the popup with no luck, still getting the numerical error, when i look at the episode it always says something like 1.781..
