TMS320F2812 target connection problem with CCS v4. (JVM terminated.exit code=1) ON Win7

Hello,
I have the save problem as melon.
I'm trying to connect TMS320F2812 board with ccs V4 ( ver 4.1.2.00027) using XDS510USB on Win7.
After that I execute Target- Launch TI Debugger and Debug window shows up.

Then I execute "Connect Target" but CCS v4 suddenly closed and error message shows up as below.
