Hi Eddie,
Well it has sort of worked but in the manner you have suggested.
I found the cache in the roaming folder, but could find no cache in the local folder of inimanager.
I tried starting the ini manager, and it did work. I could put an item into my basket but all i got was the rotating symbol. I closed the manager down and it would not reopen at all, unless i shut the pc down and restarted. but same result as before .
I decided to uninstall inimanager and noticed that the inimanger folders were still present in roaming and local so i deleted them and reinstalled ini manager which kind of worked as I had to completely add my details .
Which brings up another question .
Why do you need my simbrief user name or profile? On adding one of those the program runs and i can get the cart to open and pay as per normal.
