I have already tried this, but the problem persists.
EDIT: Also, the Adobe Font Test showed no issues with any of my fonts.
You say you're up to date, but let's verify you are running version 8.0.1.
Is there anything in event viewer?
Span/split columns can be problematic. I think, maybe, I remember a bug that was related to a specific number of columns in the frame. Do all the frames have a particular column count?
I've found that making changes to Span Columns is problematic in long documents - if changes in the paragraph style cause reflow, especially overset text at the end of a long doc, it's as if it's too much for ID to handle. One potential workaround is:
1) Copy a small bit of text set in the problem style to a fresh document
2) Make the changes you want
3) Save & close the new doc
4) Import the style from that new doc from no. 3 above into your long doc
It works, sometimes.
(What works better is not using Span/Split columns - it'd be a great tool if it was reliable, but it's simply not reliable.)
Thanks for your replies.

All of my frames have 2 columns, and the error only occurs when switching from span, to single. This is the log from the Event Viewer, although it doesn't provide much to work with:

Unfortunately the import style trick didn't work, but it was a good idea. Like you suggested, I will be staying away from the span options from now on.
I ended up deleting all of the paragraph styles to get things moving again.
If I remember a span/split problem, it wasn't associated with two columns, not that it makes any difference.
