Problem with importing MT entries

Actually they are Typepad entries but the threads I found on here seemed to think that you treat them as MT entries.

My problem is that when I click ‘let’s go’ I get a WP page saying:

‘The file you specified does not seem to exist. Please check the path you’ve given.’

I expect it’s rather obvious to someone who knows what they are doing how to correct this, but I am learning on the job and don’t really know what I’m doing – can anyone help me please?

Thank you.
