I'm also experiencing this issue while trying to use the Latest Release 1.4.0.1. When running the setup file, I get the following error: Steps To Reproduce: 1) At the top of this page, click on Tools -> CF Song Manager, which takes you to ignition.customsforge.com/cfsm. 2) Once at that page, scroll down and click on the "I agree to use the CustomsForge Song Manager at my own risk" check box, and click to download Latest Release (1.4.0.1) Windows. 3) Extract the downloaded file (CFSMSetup.rar) and run the setup file (CFSMSetup.exe). 4) Select Next on the first step of the install screen and the error will be shown. I noticed that @@cozy1 stated above to download the latest CFSM beta, so does that mean the release that is labeled as being the most recent stable version is now broken?
