InDesign CS5.5 freezes when creating an idml file

Good Day All,

I have been using inDesign since it started and have never come across this problem. I have a file that I intially created in CS4, converted to CS5 and now CS5.5. I have been trying to convert it to an IDML file and EVERYTIME it hangs and freezes. It actually produces a file but non-useable. I have been struggling with this for the last two days.

I have;

removed cache recovery files

looked at all styles to ensure optical kerning wasn't on (seems like a common problem)

rebuilt the file and renamed it

replaced Adobe Garamond Pro with Garamond Premier Pro

tried it on another machine

Re-installed CS5.5

I am using Windows 7 Ultimate with CS5.5 the document is about 11 pages long and packaged and zipped is 34.0Mb

I am starting to pull my hair out here!! Any help would be GREATLY appreciated.

Thanks!!

Curtis
