Thanks for posting that valuable information Colin, and it was nice to chat to you yesterday.
I have to say, new customers have been very understanding in this matter - a huge relief.
I feel embarrassed, even though the problem is not of my making (mercifully).
I will use your step by step instructions in documentation. It will save me a lot of grief.
Most of the chat on the forum is Gardening related, but there will be lots of interest for you and other Bank Genie users soon.
