Daemon tools lite + YASU

[ishallownyou]

I have tried everything people have posted before you jump to a conclusion of what I have
not done. Now here is my problem:I have daemon.exe, daemon.dll, DTpro.exe, DTpro.dll so none of those solutions have worked. My OS is Windows 7 64 bit ultimate. Even though I have done all of those things I still get "Unable to authenticate 'DAEMON Tools Lite' or DAEMON Tools Pro'." Please help me with this problem that seems to have no answer I've literally
browsed the forums and internet for 4 hours to no avail.

What' your initial problem ? Which game/app causes trouble ?
Which error message do you get (from the game/app) ?
How have you created your image ?

YASU isn't developed/supported anymore.
Even if you get it going it's not compatible with the SPTD driver anymore.
