I take it you had to resinstall Kiwi from the sounds of it. Was it a hard drive failure? on the drive Kiwi was on? Can you get to any backups if there were any?
The problem here is that kiwi is very versatile, and if you were using it for alerts then it probably had a decent number of rules setup, possibly some scripting and without backups it may be extremely difficult to get it back to where it was.
If you can't get a backup, I'll see if I can offer some more assistance when I can get to my server tomorrow.
