I tried using the infamous subinacl 'fix' - and get 'subinacl not known' even after uninstalling and reinstalling it.
As far as I can tell, the registry entries are OK anyway.
The Fixit that I get from following the guided help fixed two items first time around - and didn't fix the problem.
Second time around it fied one problem - and that's where we end up in a repeat situation - it fixes one item every time, but fixes nothing in terms of results.
Any more info needed - let me know!
Any advice gratefully received.
