Create-reapeaks-in-selected-folder.zip
Try this it will do one selected folder at a time by selecting the audio file type.
So if you select a wma file it will create reapeaks for all wma files in that folder, or if wav or m4a or aif of flac etc..

The other script would take a very long time as it batch converts, not sure what went wrong in your pics will look more later.
