UNDO 'Hide OBS from screen capture - now I cant get interface back help!

[Qbaser]

I selected a setting somehwere that 'hide OBS from screen capture' or something? Now its minimised in my tray, I can only right click to start recording etc. however I cannot now get back to the OBS settings panel. I even uninstalled and reinstalled but it seems to have remembered this and minimised again. How do I get back OBS settings panel please? Thanks in advance. Al
