i have now done it. i had to flash 5.11. onto the profilux. i then downloaded 5.1.1.3 pro control, i then re updated the vortech 1.03 even though it was already on 1.03. (previously when i updated vortech i did it on profilux 5.05 using profilux control 5.10. when tryin to use on updated profilux i was getting communication errors when trying to use the vortechs. everything worked fine after firmware updating profilux and profilux control then firmware updating the vortechs on this programme rather than 5.10. for anyone getting communication errors after upgrading profilux control try updating all pab devices on latest software
