I've been experiencing the same thing as the rest...didn't know what was causing it till I read through this post.
I just wish I would have read it sooner...would have saved me alot of time uninstalling and reinstalling.
I use a firewire external hard drive for all my kma files. It's aways plugged in when I start hoster so I didn't figure that was the problem. But when I tried starting hoster earlier today, I got the dreaded message. After reading through this post, I tried disconnecting the external drive. No help.
Then I pulled out my wireless pcmcia card and voila, that did it. Hoster started up fine. No reinstall necessary.
And as you can see, plugging the card back in AFTER hoster started is okay.
What a relief!
