I downloaded Drog's Arcanum_OST_Lossless.exe and HQ_Music_WAV.zip. However, it's not working. Also, I downloaded this from http://www.terra-arcanum.com. Terra-arcanum seems to be the go-to site for the mods, which is why I think it should be legit. (Also, I did read the sticky but slipped and did so after I posted. I'm on about 4 hours sleep so if I shouldn't have created a new thread, my apologies.) Anyway, I also scanned for viruses, and none were found.

I think it may not be working due to me blocking something. However, I'm not sure if I should stop blocking it... Attached is a screen-shot of what my firewall's telling me. But, here's a transcription of what the message says in the image:

"Arcanum_OST_Lossless.exe could not be recognized and is about to modify the protected registry key HKUS\S-1-5-21-3368047252-2430471514-115946973 6-1000\Software\Microsoft\windows\CurrentVersion\Internet Settings\Connections. You must make sure Arcanum_OST_Lossless.exe is a safe application before allowing this request."

Is that request by the .exe normal? If so, why? I'm not sure if this is a dumb question, but I'm puzzled by it needing to modify internet settings, and I don't want to allow it through my firewall until I understand. I don't get why a soundtrack mod would need to change a registry key for internet settings.
