Launcher Problem

[CaffeinatedPixels]

I'm trying to start the Demo and every single time I run it this pops up:

---------------------------
Lua Error:
---------------------------
Step() failed!: [string "--client\functional\TimelineManager.lua..."]:341: attempt to index global 'ModelDesigner' (a nil value)

You can CTRL+C on this to report it.
---------------------------
Retry Cancel
---------------------------

I've reinstalled, redownloaded, patched registry, etc, no avail. Any help would be appreciated. Thanks.

Lots of people seem to be encountering this error. Delete the game. Delete the folder in your documents, delete the registry entry. Manually download the game, and run the manual download located here: viewtopic.php?f=16&t=1271
