Sorry to hear you are having trouble.
Icons will not install on desktop and for some reason its keeping icons from other non stardock programs from installing Icons on desktop.
Not sure what member app you are referring to here (IconPackager perhaps?). If you are still wanting help there, please add more details.
If you are still wanting a refund, you can use the link provided and you do not have to log in - just use the options below and you can still submit a ticket.
