Hello all
Pleas help me in this case.
Best regards in advance.

Re: Error in NodeRecorder
it is a strange error that probably has to do with some funny character in that first recorder command that is not showing up when you look a the line. comment the line out, i.e. # before it.
retype the command as you have it on the net line, don't cut and paste.
