Finally found a solution for me at least, here is what just worked for me.
Went in to my C:\Users/(your users name )/AppData/Local + C:\Users/(your users name )/AppData/Roaming & deleted the iniManager folder in both locations.
I also did a regedit search for inibuilds & deleted the old reg keys I found (might not be necessary & this Can Be Dangerous so Do at Your Own RISK)
Reboot my PC, downloaded a fresh copy of the inimanger software from inibuilds then installed using "Run as Admin"
This has finally allowed me access to a working A350 & the airport updates I had missed, hopefully this can help other users
