[TenTec] Omni 7 ethernet port and One Plug program problems?

[Denton]

Hi all..gotta a couple of problems with my slightly used Omni 7...and I 
don't think it's the rigs' fault.
When I try to run One Plug, I get a "run time error 13, type mismatch" 
message on screen instead of the programs start gui.
When I try to hook up a cross over ethernet cable to a second ethernet port 
in my pc to the Omni 7, the port and omni seem to talk to one another, but 
no data flows, irregardless of deligent internet address designation in the 
Omni's menu.
Any workarounds? will probably call TT later this am....
