As I said earlier, you'll need to open it in a command prompt. Or you can download either of those ROF files that Naulahauta uploaded and edit the batch file to have the name of that file (at the moment it says Effects_000000.rof), then make sure the EXE, the BAT, and the ROF are all in the same directory and run the BAT.
If I can be bothered I may try making a GUI for it later though, to make it easier for everyone to use it
