Visa Interactive Control Error for NI 9871 with NI 9149

Hello,

I am having problems connecting to the serial ports on the NI 9871. I have followed the tutorial here (http://digital.ni.com/public.nsf/allkb/F3AB0B5D7DBA367C86257982005BBF2C)

and have gotten the server running. However, when I try to select the 9149, the following error message pops up.

However, I can see the com ports within max but not in my project manager (shown below).

Additionally, when I try to access the ports through the VISA resource name in the block diagram, nothing shows up.

Thank you in advance!
