I had to uninstall the Pro-DS plugin from my computer because it was causing Ableton to crash. I'm currently trying to reinstall the plugin, but every time I try to open the downloaded file, I get an error message that says "the following disk images could not be opened" and under reasons, it says "image not recognized" and thus, I cannot install the plugin. Any help with this would be greatly appreciated.
