Vi Logger 1.1.1 Digital channel as trigger for logging

Hi,

I need to use a digital channel as start trigger for logging using Vi Logger 1.1.1.

I define a digital channel as indicated, but it does not appears in Task attribute for "Logging conditions" on the list box "Digital channel name".  It appears "<No configured channels>". The channel does not appear as Virtual Channel either.  Is it  a bug of this version?  or What I have to do?

I know Vi Logger is a very old one application, but my hardware works with it only.

Could some help me please?
