Just FYI, if you set PlexAmp to be on your taskbar and an upgrade becomes available, it will remove the taskbar link during the upgrade. I can understand why this is happening (the uninstaller is just doing everything and the kitchen sink), but it’s pretty weird since most other apps that upgrade don’t do this and try to preserve the links you set. Still love PlexAmp! 
Workaround: keep resetting the PlexAmp taskbar link after upgrade.
Thanks!
