When I reopened it a few days later, I tried to check my web site ranking and when I clicked on the button to initiate the tool, the program crashed with a Visual Studio Just In Time debugger box indicating an unhandled win32 exception occurred in ds.exe.
I have VS 2005 installed and used the debugger to have a look at the assembly code, and the error captured was an access violation.
After doing some searching I found that Data Execution Prevention sometimes causes this problem, so I have disabled this but the problem still persists.
Can anyone point me in the right direction?
