Well that's good that playing ability is back. I don't know why Speed test doesn't work at this point. The link I posted was messed up. I just re-edited my post. If you haven't tried it, it's fixed now. But it sounds like you got it resolved anyway. If you mean your Nero burn software doesn't work, that could be reinstalled.... I wouldn't worry too much about getting Nero speed test to work because it's only an indication of the maximum speed your system can do, but won't prove how fast you can shrink something. And some people think it's fun to see the results. But if it's too frustrating, or doesn't work, you don't really need it anyway.
