[Dx4win] Error on packet window

[n3drk]

Everything is doing fine on my upgrade from version 5.03 to 6.03 with one
exception. Whenever I try to login to any TCP/IP packet cluster I receive an
"Error" dialog window which states " Exception occured. Apro Exception" and
nothing comes up. Can someone clarify to me what is happening here? All my
preferences from the previous version have been successfully merged as far
as I can tell.
Thanks and 73's
