Make sure to move your Kma folders to ext. Drive FIRST.
Due the registry cleaner after removal of your Hoster program and all folders.
I think your MAJOR problem is that your previous installes are causing a conflict in Hoster so cleaning all folders out will give you a Total clean install.
If you don't have a registry cleaner here is a very good one that I use.
