This issue was fixed. No litecoins, kilohashes or mining profits were lost.
Thank you.
But please try to sort out a better way of communication, I had nothing to think but the very worst and it took the intervention of someone I know to sort out. If I'd have been on my own with this, I'd have been stuck.
Again though, thank you.
I will endeavour to delete etc.
