Mod Manager fails to run after updating it

[Simon34545]

I downloaded the latest release of the mod manager, as the old one was causing studio to tell me the studio files are missing or corrupted. However when I run the latest version nothing happens. After looking at the event viewer it seems it exits with this error:
