WidevieW and Windows 7 not communicating at all

i have two PC's with i5 processors and 8gb ram each. i have 4 monitors but cannot get WidevieW to communicate across the Windows 7 network. File sharing between the 2 PC's is no problem in NetBIOS or Homegroup. I have tried all possible network variations within WidevieW FSX (i.e. set binding to '0' or enter gateway IP). Nothing seems to work. my Firewall as well as ESET Smart is configured to alow TCP/IP communication over home network)
Wideview Helpfile and email support is of no great help.
Any suggestions?

thank you - Marco
