Hi James,
If you are having problems can you send an email to linkplanner.ptp@cambiumnetworks.com and we'll investigate the cause. It would help if you include details of any error messages that you see.
There are no issues with the path profile service at this time so any problems are probably caused by incorrect network settings on your computer. Check out this guide for more information: http://community.cambiumnetworks.com/t5/LINKPlanner-FAQ/How-to-Obtain-Path-Profiles/m-p/38869#U38869
Thanks,
Andy
