PS Script disabled on this system?

I'm trying to run a PS script and getting the message below.  I thought the fix for this was to run, "set-executionpolicy RemoteSigned" & "Set-ExecutionPolicy Unrestricted".  I've ran those commands, hit "Y", but sill, I get the message below. Win7 64 bit machine.

File C:\Test.ps1 cannot be loaded because the execution

 of scripts is disabled on this system. Please see "get-help about_signing" for

 more details.
