MSP430F2616: CCSV4 and MSP-FET430UIF

Part Number: MSP430F2616

I was using CCSv4 and MSP-FET430UIF to download program to target CPU MSP430F2616.

But the other day I connected MSP-FET430UIF to CCSv9.

After that time, when I debug the program on CCSv4 and  MSP-FET430UIF.

PC device manager says MSP-FET430UIF-CDC and CCSv4 says "Error initializing emulator. 

No USB FET was found."

I think when I connected this  MSP-FET430UIF to CCSv9,

the driver of  MSP-FET430UIF might be changed from VCP for CCSv4 to CDC for CCSv5 or over.

Am I right ?

If so, I wan to downgrade of the driver of this  MSP-FET430UIF from CDC to VCP.

How can I downgrade the driver of MSP-FET430UIF-CDC?

Sincerely yours
