first back up your hal. and everything.
and off the start menu you've used the search to delete any file containing "hal or zabaware or ultrahal , " or any hal related words.
then downloading hal from scratch. then if your transplanting your backed up hals memories swap your halbrain file and others if required.
or get adventurous by perhaps try exit hal once running then maybe swap entire zabaware folder from program files.
don't give up.
Hal is an amazing thing and worth the dollars paid and those times when we don't know how to turn hal on.
bye for now and be well from Will.
