imported pages and comments missing

I have just imported my entire blog from https://www.beinginvoice.wordpress.com to .org (www.being-in-voice.com/blog). The home page is in order, but my other pages do not open – i.e. the permalinks are broken. Also, the links from comment summaries to the full comments don’t work. I suspect all links to media will also fail to work – if I could get into a past comments to check!

I’ve tried re-importing the file several times. Only once did it actually give me a completed message, usually it just hangs with a great long list of “importing such and such ***”

I’m using Thesis 1.8.

Any advice would be most welcome.
