I've compiled a new version, it can be downloaded now.
My apologies for the inconvenience. I had made a change to the Stereo Tool processing between versions 3.13 and 3.14, but I never realized that it would impact the command line version also. So I completely forgot to test it before uploading it.
As in "It builds, let's ship it"...
I will add an automated test of the command line version which will be ran automatically before a version is uploaded to avoid this type of problems for future versions. Thanks for notifying me of this problem.
Note: When using the command line version, you need to specify the FULL PATH to the sts file. So .\Profile.sts won't work - you really need to use something like C:\blabla\Profile.sts ! (For the input and output files, you can use relative paths without problems).
