That looks like a bug in the program - trying to open v39, which doesn't exist. (Even though the ROM is v39, that doesn't mean everything in it is - audio.device, for example, is still v37 in v40 ROMs, so an attempt to open audio.device v40 would fail similarly).
It looks like your Google results turned up a changelog for a newer version of the program with the bug fixed. Try to find that version of the executable.
