Q: I use a Bruker Avance 400 III, when using topshim command the following error appear: 'wait for event-acquisition running:timeout after 20 sec' Any ideas? Thanks!

The problem seemed to dissapear completely after a firmware upgrade of the ELCB. Make sure that you have the most recent firmware that is compatible with the Topspin version that you are using (We have TS 3.1).
