Hi oz
There is no 0.2.5 money module out there yet

I'm currently working on 0.2.4.2 where this exception is caught correctly so that at least the simulator will startup without terminating.
But the reason for this is actually located somewhere else. If you e.g. remove temporary the module from bin, it might startup, but will print many errors when there is any xmlrpc call (e.g. search update, group information, profile, etc...).
This happened to me lately also on my dev server. Unfortunately I could not localize this issue exactly, but my suspect is that it might be located in mono. Uninstalling and reinstalling it (2.10.6 here) solved it for me, allthough I am not sure what it was exactly ... :/
