The use of the word "import" worries me. Did you use the CodeWarrior IDE's File > Import choice, or did you follow the instructions in the Freescale USB Stack with PHDC Device Users Guide? I am going to assume that you followed the guide for now, because if you did, you still will see that error.
That's because to confirm the problem, I downloaded the guide, the USB stack, followed the directions, and got the same error.
As a side note, the .launch configuration file is not located in the Project Settings folder, but in the Debugger folder now. Assuming you figured that out, then the next hurdle is correcting the file path for both the memory and initialization files. Proceed as follows:
1) Call up the Debug Configuration window (Run > Debug Configurations) . Select the desire debug configuration. Under the Remote System group, for the System option, click Edit.
2) In the Properties window that appears, Click on the System tab.
3) Under the Initialize group, for the Initialize Target option, click on the navigate button. (It has the ellipsis character "...".)
4) Navigate to the initialization file, init_kinetis.tcl. It's located on the path:
C:\Program Files\Freescale\Freescale USB Stack v3.1.1\Source\Device\app\hid\cw10\kinetis_k60\Debugger\init_kinetis.tcl
Your path name may vary, of course. Click OK.
5) Under the System group, for the Memory Configuration Target option, click on the navigate button.
6) Navigate to the memory config file, iMK60N512VMD100.mem. It's located on the path:
C:\Program Files\Freescale\Freescale USB Stack v3.1.1\Source\Device\app\hid\cw10\kinetis_k60\Debugger\MK60N512VMD100.mem
Your path name might vary. Click OK.
7) Click OK to dismiss the Properties Window.
8) Click Apply in the Debug Configuration window to save your changes.
You should be able to download and run the application now.
