When a pose file moves the location of a character it usually does it by translating the hip actor. Try this solution, with the character in the location you want it in, select the hip and do Ctrl+C (or "Copy" from the Edit menu). Paste the results into Notepad, you should get something that looks similar to this:

Hip 0       taper   Spline  0.0000<br></br>Hip   0       scale   Spline  1.0000<br></br>Hip   0       xScale  Spline  1.0000<br></br>Hip   0       yScale  Spline  1.0000<br></br>Hip   0       zScale  Spline  1.0000<br></br>Hip   0       yrot    Spline  0.0000<br></br>Hip   0       zrot    Spline  0.0000<br></br>Hip   0       xrot    Spline  0.0000<br></br>

Copy the last three lines, the ones shown in red above, to the clipboard. Apply the pose. Now with the hip selected, paste from the clipboard (Ctrl+V). The hip should return to its previous location.
