The fix I mentioned is available to all as of last night. Update Inner Space to build 5388, first of all. (just close and restart and let it patch up)

Then, grab the ninja patch of ISBoxer 38 (it will be a pushed update later this weekend for whoever doesn't download it manually). Direct link: http://www.lavishsoft.com/downloads/...erSuite.38.exe

After installing both updates, do a fresh Export and you should no longer experience this issue
