Invalid opcode in GDS for Ref demo

[JackNWhite]

Hi,

I have followed the Ref tutorial for F' 2.1.0 and I am trying to send it a math operation, but I always get an invalid-opcode event in response to mathSender.MS_DO_MATH 1.0 2.0 ADD.

Edit: I should say that I changed the base ID of MathSender to 1100 (0x44c) instead of 1000, because that conflicted with this:

<instance namespace="Sys" name="resources" type="SystemResources" base_id="1000"  base_id_window="100" />

Any ideas?

I think I neglected to register the commands.
