Sometimes GPU PerfServer can get wedged. If you are having problems connecting, close GPU
PerfStudio, and close GPU PerfServer by right clicking on the tray icon and selecting Exit.
Next, restart GPU PerfStudio and then restart GPU PerfServer using the desktop shortcut or Start
Start->All Programs->AMD->GPU PerfStudio 1.1->Restart Performance Server.
The easiest way to get this working is to make a shortcut to your application, complete with command line options. It's then just a simple case of dragging the shortcut onto the GPUPerfStudio server.
