couldn't insert file index 0?
can't open update.rlb! aborting!

Tried running as admin, deleting the update.rlb file, reinstalling..

Running on Windows 7.

If it helps - it seems to stop downloading at exactly 8kb every single time..

Have also tried a few compatability mode options. This game looks like exactly what i'm after.. but I can't even play it haha :(

Used a different internet connection - for some reason vividwireless in Western Australia seem to block traffic for this? Does it use P2P?
