I think the problem is the OP just overwrote his Tango-fied sc.ini with 
the stock DMD one.

After I unzip a new dmd version over top the old one, I run my 
"usetango.bat" script which looks like this these days:

----
@ECHO OFF
echo Setting up DMD environment for using Tango runtime libraries...
copy "%DMDDIR%\dmd\bin\sc.tango.ini" "%DMDDIR%\dmd\bin\sc.ini"
copy "%DMDDIR%\dsss\etc\rebuild\default.tango" 
"%DMDDIR%\dsss\etc\rebuild\default"
ren "%DMDDIR%\dsss\include\d\std_tango_" std
ren "%DMDDIR%\dsss\lib" libphobos
ren "%DMDDIR%\dsss\libtango" lib
echo Done.
----


Note that I keep a copy of the tango version sc.ini in sc.tango.ini.


And here's the corresponding usephobos.bat too:
----
@ECHO OFF
echo Setting up DMD environment for using Phobos runtime libraries...
copy "%DMDDIR%\dmd\bin\sc.phobos.ini" "%DMDDIR%\dmd\bin\sc.ini"
copy "%DMDDIR%\dsss\etc\rebuild\default.phobos" 
"%DMDDIR%\dsss\etc\rebuild\default"
ren "%DMDDIR%\dsss\include\d\std" std_tango_
ren "%DMDDIR%\dsss\lib" libtango
ren "%DMDDIR%\dsss\libphobos" lib
echo Done.
----

I also keep a copy of the default phobos sc.ini in sc.phobos.ini.


The only problem is if DMD changes what it puts in sc.ini.  But I don't 
think that's happened in a long time.
