Hi,
What issues are you still having? The steps to troubleshoot the issue are pretty complex and might need to be performed by your IT staff.
Go to the task manager, processes tab and locate the PID (Process Identifier) for C1LiveUE.2.EXE (By default in Vista or XP, you will have to go to View, Select Columns, and add PID as a column to be viewed)
Once you have the PID, go to the command prompt and run netstat -ao
Look for the entry in the list that matches that PID and find the foreign address that it is connecting to. It should say something like "Site1: http" or "10.0.1.220:80" meaning that it is using the HTTP routing or Port 80 on your machine.
I'm attaching a spreadsheet of an export that shows what it should look like.
