XDS510-USB2.0

Hello
I have a TI DSP EMULATOR ( XDS510 USB2.0 ) .
I want to test connecting the CCStudio v3.3 to EVMOMAP-L137 with the Emulator .
I installed  XDS510-USB2.0 driver and run   E:\XDS510 CCS Driver \ Setup.exe  and E:\CCS Software\ccs3.3\CCS_v3.3_SR11_81.6.2\CCS_v3.3_SR11_81.6.2.exe from the emulators CD.
But when I chose "F2407 XDS510 Emulator" in code composer studio setup and save it , this error appears when i am going to start CCS :

"Error initializing emulator

I/O Port = 240

Board Name: F2407 XDS510 Emulator
Cpu Name: CPU_1 "



and when i chose "F28335 XDS510 Emulator" in code composer studio setup and save it ,  ,the CCS  will start but this error appears when i am going to connect :

" Error connecting to the target:
Error 0x00001200/-1145
Error during: OCS, Target,
Unrecoverable emulation error

I/O Port = 240

Board Name: F28335 XDS510 Emulator
Cpu Name: CPU_1 "

And when I use SDConfig and I want to Verify emulator connection ( Configuration -> Verify ), this error apeares :

  >> XDS510-USB Emulator not connected/enumerated

  >> Could not open emulation connection

Would you please help me ? are the problems about the CCSv3.3 driver ? how  can I resolve them ?
