IamNicklaus: .
Sorry Steve, I was replying to them one by one and you were next, but then the computer decided I should install a Windows update, and I stupidly thought that might help (DUH), and then my missus put dinner on the table, so I never got to you.
I can't remember everything you wrote, and I probably am desperate enough to have given it a go, but the crux of it is, there's not actually an issue starting the app, it's just that when it gets to a certain point in the loading process it just hangs and does nothing.
But I do apologise for not responding earlier - thank you for taking the time to try to help.
