miniBB to PunBB - post migration issues

G'day.

Earlier I took the plunge and switched from miniBB 1.7f to PunBB; Chacmool's super migration tool (v.1.0.4) ensured the process was a painless one--thank you, Chacmool!

After the initial jubilation, I noticed a problem: messages imported from miniBB have all lost their text formatting; the messages appear with markup tags, like in the example below:

This is a sample message content. <strong>bolding is gone.</strong><br /><br />Line breaks are ignored. <em>And no italics?</em> Uughh.

I am seeking an efficient way to restore the formatting of each post; any help/advice will be gratefully received.
