Software License Key

I went online and requested a software license key and got it via email. I opened the software and it asked me for my license key and email address.  I copied the license key and entered my email address.  It said it failed. I got another license key and it also failed.

I have the audio file recorded off of my video recorders using a Tentaclesync device.  Now trying to put it with the audio recorders file to sync them.  Can’t wait to see how this works.

I plan of maybe purchasing the Sync devices but want to see how it actually works.
