Still not sorted, Manually deleted those items from the startup. For any future visitors, here is what I did.
To remove a shortcut from the Startup folder:
Press Win-r. In the "Open:" field, type:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp
Press Enter.
Right-click the program you don't want to open at startup and click Delete.
It's a pity I had to ask for a refund. I really loved this application.
