Registry change won't stay - vcbthag.dll!! Please help

[theTastyCat]

Hi all - I'm running NueRom3 on my xv6800, and like other custom ROMs, I need to change the BTExt thing to vcbthag.dll so I can voicedial right from my bluetooth. Well, I edit the registry and make the change, but when I look at it later, it's gone back! I've double-checked to be sure I've entered it right and the file actually exists in that location, I've tried both \Windows\vcbthag.dll and \Windows\vcbthag , but no luck. It's acting like the file's not there, but it IS. I had copied vcbthag from where it began life in \Program Files\MS Voice Command\vcbthag, but it wouldn't take it there, either. I finally tried to copy the file that it defaults to and replace it with a renamed version of vcbthag, but it wouldn't let me copy that file to back it up. Grrr!!!

Any advice?

Thanks all.
