"TA X Error: BadValue" suggestions?

[Matthijs van der Meer <M.vanderMeer@ed.ac.uk>]

Greetings,

I'm working through the leabra++ tutorial in O'Reilly and Munakata, and
keep getting the following error, which renders the simulator unusable:

TA X Error: BadValue (integer parameter ... out of range)
Major op code: 18
Minor op code: 0
Serial: 717487
Resource ID: 0

Loading the recovery file does not help because it immediately generates
the same error.

Any ideas on how to stop/avoid/recover in such a situation?

Many thanks!
