PP emulator problem with CCS3.1 but not CCS2.2

Dear Friends
When I want to install the "xds510pp plus" emulator for CCS 3.1 after doing all required procedures the following message appears after setting up and running CCS3.1:

Can't Initialize Target CPU:
Error 0x80002240/-118
Fatal Error during: Initialization, OCS, Control,
This error was generated by TI's USCIF driver.

But when I install the Emulator for CCS2.2 It works properly. Do you know what is the reason?
