This is an issue affecting some Windows users. If you're currently using version 2.0.007, do the following:
- Close Syntorial
- Download https://d3s7jqmbx7395y.cloudfront.net/Installers/20013+(100)/Syntorial-PC-2.0.013-exe-only.zip
- Unzip it to reveal a new Syntorial
- Drag it to: C:\Program Files (x86)\Syntorial
- Launch Syntorial and the problem should be resolved
If you're using a version later than 2.0.007, submit a support request at the top of this page
