(yet another) "430 no such article" question

[firehousefourfiveone]

Hey - thanks for the great app! I can appreciate how much work goes into keeping this working well.

I'm having trouble with ver. 6.90 giving me "430 no such article" failures on newsgroupdirect, newsdemon, and usenetexpress. Some messages in a group will throw this error for all three servers while other messages dl fine, regardless of age (2014 through current). When I try the same message from the same servers using Forte Agent, they dl completely, but Newsbin works so much better for me in general, so I'd like to get things tweaked so I can reduce these failures. I suspect I've got setting issues. Any ideas?

Cheers,
Guy
