Error in Initializing ST-Link device

Hi, 

Just started playing around with my STM32 discovery board, and had a problem right away. I'm using atollic trueStudio IDE and trying to load a demo project(the one in firmware package), to my microcontroller. The thing is everytime I hit debug button It shows this in console:

Starting server with the following options: 

        Persistant Mode            : Disabled 

        LogFile Name               : debug_log.txt

        Logging Level              : 1

        Listen Port Number         : 61234

        Status Refresh Delay       : 15s

        Verbose Mode               : Disabled 

        SWD Debug                  : Enabled 

Error in Initializing ST-Link device

I spent entire day searching web, if I could find a solution but no success yet. I found this page(

http://www.atollic.com/index.php/kb/3-debugging/28-kb_st_link_connection_error

) on atollic website, have followed the steps but still no luck. So these are the things which I have already tried:- checked USB cable- tried running ST-LINK GDB server, same error- checked the driver installation, and updated to latest version- no disk letter issue, st link is using G: and it is vacantI have followed the user manual steps exactly still unsure what's wrong with my board. Any help appreciated. #debugging #st-link-gdbserver #driver

You might have not yet installed the ST-Link USB driver.

The discovery boards have one integrated, either the old version V1 (VL_Discovery), or the new version (V2, all later boards). Usually, a ''new hardware detected'' window pops up under Windows. Just follow it (automatic installation, no access to internet required). This drivers can also be found here:

Thank you your response, but i don't think the driver is the problem.

 Unlike the original poster, I already ran programs on the board.While I was manipulating a DB9 connector for RS232 connection, I got a bluescreen on my computer. And since that day, the same error pop-ups everytime I try to launch a debug session : http://image.noelshack.com/fichiers/2012/23/1338825285-cc.png

Bluescreens are sometimes refered to as BSOD...

Your Windows Registry might got corrupted or partially wiped out. I would completely remove the driver in the hardware manager, and reinstall it. I hope you have a backup. Perhaps you are lucky, but expect more maladies.

Addendum:

If you had this RS232 on a USB/RS232 adapter, you might have damaged that USB chip in your PC physically. Often there are more than one USB host adapters in a PC. Can you try a USB port on another driver chip ?

I tried other usb port nothing new. I even try to run the same program with an other PC and an other board, but i got the same error... If it is an error related to the code, I don't understand why, when I create a new project, I get the same problem.

If the code programmed on the STM32 is non conducive to SWD connectivity, try pulling BOOT0 High, and restart the board so it enters system loader mode.

''Error in Initializing ST-Link device

'' points to a problem with the stlink debug adapter, which is the bridge to your application, so to speak. If the host can't find the stlink, you don't have a chance to flash/debug your application.

Thank you, I pulled BOOT0 high, it works with my coworker's board, but for me, a new error appears :
