You will need to give us more detail.  What error messages are you getting?  You can search (Google works well) for the error that you are getting and find a ni.com link and you will likely get to the official page for that error.  Try what is suggested on that page first.  Then, if you still can't get it working, post back here with as many details as you can.

Here is the link to the official error page:  http://digital.ni.com/public.nsf/allkb/15AE7F234C5B966886257884006DF1CD

Also, all defaults for LIFA are for Arduino Uno, not Arduino Mega 2560.  You need to set up the inputs for Arduino Mega on Init.vi:

Board Type:  Mega

Baud Rate:  9600 (iirc)

Also try using a VISA resource constant to explicitly select the COM port that the Arduino is 'connected to'.
