Some VAmp users reported a problem using the VAmp driver while the BrainVision Recorder is installed on the acquisition PC. We experienced the same problem :
The VAmp driver can't access the amplifier if the BrainVision Recorder is installed.
In fact, the Recorder keeps running an utility called "VampService.exe", that takes control over the amplifier and prevents other software to communicate with it, even if the Recorder is not running.
We have contacted BrainProducts about that problem, and we will keep you posted

In the mean time, if this problem happens to you, the simplest solution is to kill the process "VampService.exe" in the task manager, or uninstall the BrainVision Recorder if you don't need it. The openvibe driver should work fine then.
