I downloaded a driver to video chat using oovoo from DXGUSA.com. The microphone wasn't working so I downloaded the driver again. It didn't work at all. So I deleted all the drivers i downloaded online and (i think) i uninstalled the driver from the CD-rom. I have tried uninstalling/deleting and reinstalling/downloading the driver but nothing will work. Also, my User's Manual says DXG-305V but when i download the driver it says DXG-503. Both are options on dxgusa.com to download...which one am i supposed to use?? Please help!!!
