CCS connection with Matlab

Hello

I am new to the CCS environment and know hardly anything about TI's DSP
Processor. Hence I tried dumping the code using MATLAB's C2000 embedded target
toolbox. I have installed in my computer CCSv3.1, CCSv3.3 and CCSv4 with Matlab R2012a. 
I have installed all the 3rd party tools required but cant still configure correctly.
when i run the configuration for CCS v4

checkEnvSetup('ccsv4','f2803x')

1. Checking CGT (Texas Instruments C2000 Code Generation Tools) version
   Required version: 5.2.1 to 5.2.3
   Required for : Code generation
   Your Version : 5.2.1
   ### Setting environment variable "C2000_CGT_INSTALLDIR" to "C:\Program Files\Texas Instruments\C2000 Code Generation Tools 5.2.1"

2. Checking DSP/BIOS (Real Time Operating System) version
   Required version: 5.33.05 to 5.41.09.34
   Required for : Code generation
   Your Version : 5.33.05
   ### Setting environment variable "CCSV4_DSPBIOS_INSTALLDIR" to "C:\CCStudio_v3.3MCU\bios_5_33_05"

3. Checking XDC Tools (eXpress DSP Components) version
   Required version: 3.16.02.32 or later
   Required for : Code generation
   Your Version : 3.22.01.21

4. Checking CCS (Code Composer Studio) version
   Required version: 3.3.83.11
   Required for : Automation and Code Generation
   Your Version : 
   Incompatible version detected. CCS version does not satisfy product requirements!

5. Checking 2803x C/C++ Header Files version
   Required version: 1.21
   Required for : Code generation
   Your Version : 1.21
   ### Setting environment variable "DSP2803x_INSTALLDIR" to "C:\ti\controlSUITE\device_support\f2803x\v121"

6. Checking Flash Tools (TMS320F2803x Piccolo(TM) Flash API) version
   Required version: 1.00
   Required for : Flash Programming
   Your Version : 1.00
   ### Setting environment variable "FLASH_2803X_API_INSTALLDIR" to "C:\ti\Flash28_API\Flash2803x_API_V100_CCS3.3v"

in point 3 it does not recognize the latest CCS installed. And then when I run the configuration for CCS v3.3, it does not recognize the tools installed or CCS, even as shown previously, they are correctly installed.

Could you point me in the right direction please?
