MSPFlasher can't erase/download in SBW2 mode

Hello everybody!

We use MSP430Flasher software to download our program into MSP430F6721 in SBW2 mode.

When we send a command "MSP430Flasher.exe -m SBW2",

we get a result:
* -----/|-------------------------------------------------------------------- *

So, as we can see emulator can connect to the device.

When we send a command: "MSP430Flasher.exe -m SBW2 -e ERASE_ALL -w Target_m.txt"
We get an error:

When we send a command: "MSP430Flasher.exe -m SBW2 -e NO_ERASE -w Target_m.txt"
We get an another error:

But when we use  "Lite FET-Pro430 Elprotronic" with the same libraries and the same mode - everything goes fine (see the picture):

We have already tried to use the newest version of MSP430Flasher software, and upgraded the firmware of programmer - no success, we're just getting the same errors.

What can be the reason of such behaviour? An how to resolve this problem in Flasher?
