Floating License Problem

I am not able to gwt CCS to use our floating license server. When I initially installed CCS, I was prompted to select a license source. I selected our license server and CCS accepted the selection. I later reinstalled CCS and was not prompted for the license selection. CCS says (Licensed) on the top bar, but I can only run the debugger on the evaluation board - if I try and run the debugger on my own hardware I get a licensing error. If I select Help -Licensing Options - Specify a license server and enter the address and port, CCS accepts the input but if I check again, the setting has reverted to "Specify a license file". LM_LICENSE_FILE is set correctly and I use several other programs that access the licnes server without problems.
