Error with motor imagery scenario acquisition

[nanton]

Hello,

I'm trying to implement the Open VIBE motor imagery BCI scenarios in a research project using an Open BCI 16-channel headset. I am able to execute scenario 0 and am monitoring the signals which all seem to be running appropriately. However, I'm unable to execute scenario 1 for signal acquisition and am receiving the following error messages:
[ INF ] At time 0.000 sec <Box algorithm::(0x00000de5, 0x00006f3d) aka Graz Motor Imagery BCI Stimulator> Lua script terminated

I'm not sure what the error is, and would appreciate any insight on what could be preventing the execution of this scenario.

Thank you in advance,
