I was wondering if it is a JAVA issue (being too new a version for AC11) but you said you have reinstalled AC11 itself - I would have assumed you would have had the same problem with that as well.
Maybe uninstall all JAVA and then install the JAVA version that is on the 11 disc.
Then you can update JAVA again after installing the hotfix.
Is the hotfix file a good download? - the one I have (for AUS version) is 72,596 KB.
Yours should be around the same size if not exactly the same.
