Moak: You were posting while I was typing. That's not a corrupt hostcache, it's one from a client prior to 1.12. My guess is that someone (probably) trying to help, posted their hostcache in the hostcache thread without bothering to make sure they were running 1.12, you downloaded it, and XoloX couldn't make sense of it because it was from an old version. (Does the setup handle the file compatability conversions, or woudl settign "firttime" to 'true' make XoloX check the data files for compatability?)
